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.
It’s not so much about Python itself but the libraries it uses. I experienced very often that the module maintainers for specific libraries require time to port to a newer Python version, and if it only means testing it against it. This is why I have the habit of staying on “2 version older” than the current release. As a data scientist this always made sense for me, I cannot count the times an environment broke because there was a conflict with the Python version. I guess you are right and it probably runs fine. I just wanted to set up my development environment right the first time to save some struggle later. Thanks for your input.
