Too bad hydrurga had to leave. She/he is very helpful and smart. Following up on her/his suggestions, try the following:
Code:
sudo apt purge cups cups-bsd cups-core-drivers cups-daemon mime-support opera opera-stable
Then, if it works, try
Then, if that works, reinstall the ones that hydrurga cited as important.
Code:
sudo apt install cups cups-bsd cups-core-drivers cups-daemon mime-support
Good luck!
