access to my user session on debian "failed to load session cinnamon"
Hi people, I was traied to update my python version using some commands that I'd found on google. When I tried to login to my session again, it print a message with "failed to load session cinnamon". I've searched a lot of answers for this problem but I did not get success. I tried to execute:
1 - restart - failed
2 - type follow commands on tty (it also failed): 2.1 - sudo apt-get update && sudo apt-get upgrade 2.2 - sudo apt install cinnamon.
After trying to install cinnamon, it responses to me some curious messages: "Follow signatures could not be checked besides public key is unavaiable: NO_PUBKEY 7FCC77D46ACCC4CF8" "The repository http://www.rabbitmq.com/debian testing Release does not have a Release file" "An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://apt.postgresql.org/pub/repos/apt bullseye-pgdg InRelease: The signatures......"
Although I do not beleave it could be the problem, can someone help me with it?
Thanks and Regards
