For example, I’m using Debian, and I think we could learn a thing or two from Mint about how to make it “friendlier” for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be “the universal operating system”.
I also think we could learn website design from… looks at notes …everyone else.
I do not recall other distros failing to update due to GPG key issues but it has happened to me on Arch distros many times. It is the biggest pain when converting from something like Manjaro to something like EndeavourOS as well.
I really do not understand why this cannot be fixed.
