TLDR: I need to restore my distro after sudo removing all Python dependencies

I did the stupid thing and now I need to fix it. I wanted to do a clean install of Python for a class, uninstalling all programs that I installed using the command our teacher gave us (basically, remplacing apt-get install in the line he gave us to install Python with apt-get remove). So I ran the following:

sudo apt-get remove python3 libfreetype6-dev python3-pip python3-virtualenv

And, not paying enough attention to the list of dependencies that were going to be deleted, I went on with the command. Now I am left without Kubuntu, but KDE is still installed (it seems so, at least): I can still use the GUI + access Dolphin, Discover... I also installed Mozilla using sudo apt-get install without any issues and can go on the internet. In turn, it seems like apt-get is working. I haven't tried anything since.

This topic has been adressed a few times :

Instead of asking the same question once more, I'll ask what's the best way to go around restoring Kubuntu 20.04 after sudo remove-ing Python? There seems to be three ways to do this:

sudo apt-get install --reinstall python python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

sudo apt-get install --reinstall python-dnspython

sudo apt autoremove

sudo apt-get -f install

This would reinstall everything python-related that I've deleted and then I should be able to reinstall Kubuntu without any issues. But I'm not sure I should run autoremove since there's a huge list of extra packages that would be removed. Any extra input on that matter?

  • (no. 2): Installing the entire list of packages that I deleted running my apt-get remove command. The list comes from /var/log/apt/history.log (see bottom of the post for the list, it's a long one). Would this restore everything, or would reinstalling them (using apt-get) somehow change things from the way they were before? There is also a list of packages that are not longer used since running my sudo apt-get remove command, which apt-get recommanded me to get rid of using autoremove (smelling something fishy I did not run autoremove!) (I can update my post with this list, if it's of any use).

  • (no. 3): Doing a clean install of Kubuntu from a live USB key. It seems overkill, but since I saved all my files to a hard drive before trying to solve my problem, it wouldn't be too much of a hassle.

Which option would work best / be the easiest? Obviously, I'm pretty unexperienced with the command line (although a very enthusiastic Linux user), so the easiest option would (no. 1) would be the best for me. Anything else I should be watching out? Thanks so much for your input !!

There is no "best way".

sudo apt install kubuntu-desktop^ should do it. If it does not work, you will have to reinstall.

Never mess up with the default python. You can install additional versions of python and use a virtualenv.

  • Thanks ! I guess I learnt not messing with Python the hard way... I'll try this and if anything seems to be malfunctionning, I'll keep the list of deleted files at hand and reinstall them. Do you know wheteher I should avoid running autoremove so I don't delete anything extra?

  • First install kubuntu-desktop. Unless you remove important meta packages, autoremove should not remove any required packages. Jul 28, 2021 at 12:45
