Hello about two years ago I tried updating python and something went very wrong. I am now trying to update my distro and I am running into a bunch of problems. I don't use this laptop often and I don't know Linux all to well. I have been checking the forums but so far nothing has solved my problem. I have gathered some information and I hope I have enough to properly relay my problem. It seems that perhaps the environment variable got deleted. It also appears I have multiple python versions installed and I tried to set aliases a few years back. But I clearly broke something because the terminal doesn't work and I can't update my ubuntu version.
Hopfully there is enough information below to help resolve my problem of trying to upgrade my distro version and getting python working again.
My ubuntu version
