I wanted to start contributing to an open source software project yesterday evening, and they recommend virtual box to not mess with your default installation of the program and the databases it uses.
So I thought Debian would be a nice clean distro for developing Python... Gnome feels really unusual to me and I hate it, I guess I can replace it with KDE.
But I couldn't install a specific Python version? System python is 3.13 but I needed 3.10. I tried adding the deadsnake ppa but Debian didn't know the add-apt-repository command. So I tried to install software-properties-common which also failed because the package couldn't be located. Someone on SO said it was removed because security but I mean wtf? So the solution is to add this package cgabbelt manually to sources.list but I couldn't get it to run because I couldn't verify the GPG key... Then I went to sleep.
I am pretty sure this community can help with the problem, but honestly, wtf? I am not a Linux power user but a data scientist who works on Linux for a couple of years now, how is it possible installing a specific Python version is such a hassle?
Is Debian just a poor choice for developing? The software I want to contribute to has many dependencies, they recommend Ubuntu but fuck Ubuntu. So I guess I can't take something too exotic.
Usually you do this with venv. I'm sure there's a cool kids way to automate everything but it's not that hard to just download 3.10 (or whatever version you need), compile it, install it into a 3.10 directory, and point your path at it.
I don't like Gnome either. I've been using MATE which is pretty straightforward, and looks like old-fashioned Windows. Not saying that's a good thing, but at least for me it had very little learning curve.
If that project requires Python 3.10 and won't work with 3.13, that may be a problem in its own right.
