Ubuntu 23.04 Messed up PPA repositories

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.

Install anaconda and set up a virtual environment for python3.10 https://anaconda.org/anaconda/python

Changing the python interpreter can be a system killer. You may need to reinstall the OS. Don't change the python interpreter on your system. Use virtual environments instead.

@ArchismanPanigrahi yea, the project I'm working on requires a separate virtualenv for pip

@Nmath right, though the python interpreter got during the system upgrade to ubuntu 23.04.

@guiverc Thanks, I think it does. Yesterday I was able to build python3.8 from source. I had the assumption that the PPA repositories always support the new releases, but it's totally up on the maintainers.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
