The logs show that mysql failed to start, but with no clear indication as of why.
Please provide clear steps to reproduce the problem. In th emeantime, I suggest the following: sudo apt update sudo apt -f install If the error persists, then please attach the terminal output again, and /var/log/mysql/error.log.
