Hi, I had the same error. I solved this by one command: sudo systemctl enable mysql
Than I had to start MySql: sudo service mysql start After this I was able to update: sudo apt dist-upgrade One could try to recreate this bug by disabling MySql before upgrade: sudo systemctl disable mysql I hope this helped you.
