  +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 Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus.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” :)

    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 Specifically, I need ROS 1 - which is no longer being updated, as ROS 2 is now the focus.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” :)

      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” :)

    +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” :)
