    +url: null
    +body: """
      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

    +title: "Can I install Ubuntu 18 software on Ubuntu 22.04? (Technically Linux Mint 21.3)"
    +url: null
    +body: """
      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "Can I install Ubuntu 18 software on Ubuntu 22.04? (Technically Linux Mint 21.3)"
    +url: null
    +body: """
      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "Can I install Ubuntu 18 software on Ubuntu 22.04? (Technically Linux Mint 21.3)"
    +url: null
    +body: """
      Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
      \n
      For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
      \n
      The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
      \n
      The course instructions generally gives 3 options:\n
      \n
      1. Install ROS on a VirtualBox virtual machine\n
      2. Install on Windows using WSL\n
      3. Install on a real Ubuntu 18 system\n
      \n
      Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
      \n
      Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

          From Wikipedia, the free encyclopedia\n
          \n
          Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
          \n
          Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
          \n
          ### Rules\n
          \n
          - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
          - No misinformation\n
          - No NSFW content\n
          - No hate speech, bigotry, etc\n

      +url: null
      +body: """
        Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
        \n
        For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
        \n
        The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
        \n
        The course instructions generally gives 3 options:\n
        \n
        1. Install ROS on a VirtualBox virtual machine\n
        2. Install on Windows using WSL\n
        3. Install on a real Ubuntu 18 system\n
        \n
        Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
        \n
        Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

      It doesn’t seem to have any outrageously complicated dependencies to work, just C++, Boost and a few other recognizable names, at least at a glance. They also seemingly have an ArchLinux package, which means it’s likely to at least be buildable on latest everything. Mint will fall in between, so the odds it’ll compile are pretty good.

          From Wikipedia, the free encyclopedia\n
          \n
          Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
          \n
          Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
          \n
          ### Rules\n
          \n
          - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
          - No misinformation\n
          - No NSFW content\n
          - No hate speech, bigotry, etc\n

      +url: null
      +body: """
        Hope these kinds of questions are allowed here. On this occasion I’m just looking for a straight answer.\n
        \n
        For a university course I need to install ROS - software for doing robotics stuff. Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus. The installation instructions are here: [wiki.ros.org/Installation/Ubuntu](https://wiki.ros.org/Installation/Ubuntu)\n
        \n
        The instructions from the course material say that only Ubuntu 18 would work, though [the ROS wiki says Ubuntu 20.04 is the target](https://wiki.ros.org/noetic). Either way, it doesn’t seem to be available for Ubuntu 22.04 and therefore Linux Mint 21, which is what I’m running.\n
        \n
        The course instructions generally gives 3 options:\n
        \n
        1. Install ROS on a VirtualBox virtual machine\n
        2. Install on Windows using WSL\n
        3. Install on a real Ubuntu 18 system\n
        \n
        Right now I’m going to use VirtualBox to get started, but I’d really prefer to run it natively and I’m worried about performance. Is there a simple way to download and run software intended for Ubuntu 20.04 on Linux Mint 21.3?\n
        \n
        Edit: thank you all for the great suggestions! I got stuck on an unrelated problem (ran out of storage space) but I’m sure your suggestions will work once I fix that. Forgive me for not replying individually, you’re all awesome and I don’t have anything to add other than “thank you” :)

      It doesn’t seem to have any outrageously complicated dependencies to work, just C++, Boost and a few other recognizable names, at least at a glance. They also seemingly have an ArchLinux package, which means it’s likely to at least be buildable on latest everything. Mint will fall in between, so the odds it’ll compile are pretty good.
