All my hare-brained development ideas are more or less sandboxed in Docker containers. Rarely I need to schlep out to Sourceforge to get the right app for something. Most of the time there’s an apt or flatpack thing for what I’m up to, but I do go on a spree purging all that from time to time.
My only complaint is with Nvidia driver support/quality/maintenance, but I get that’s not Canonical’s fault.
