Recently I upgraded from Ubuntu 22.04 to Ubuntu 23. After the upgrade, I noticed that the default python3 was also upgraded to python3.11. I tried to install an older version of python through apt, but I kept getting
E: Package 'python3.10' has no installation candidate
I tried to solve it by changing the name of the PPA repositories to the new version in the sources.list file
❯ sudo sed -i ‘s/jammy/lunar/g’ /etc/apt/sources.list
After the above command all the repos were unchecked from the "Software & Updates" app/settings.
Software & Updates -> Other Software
If I manually enable the deadsnake one (the one that should have python packaged), I'll get the following:
Reading package lists... Done
E: The repository 'https://ppa.launchpadcontent.net/deadsnakes/nightly/ubuntu lunar Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I feel like I messed this up quite bad.. Could anyone help me figure it out?
Thanks.
EDIT: I ended up build ing python3.8 from source. Looks like the repository that I used previously doesn't support the new Ubuntu 23.04.
