Po aktualizacji do Ubuntu 16.04 zauważyłem, że mysql ma zadziwiające błędy. Przekonany, że to była zepsuta konfiguracja, próbowałem uruchomić czystkę mysql. To nie wydawało się usuwać wszystkiego, więc próbowałem to zrobić sam:
sudo rm -r /etc/mysql
sudo rm -r /usr/share/mysql-workbench
sudo rm -r /usr/share/mysql
sudo rm -r /usr/share/mysql-common
To był błąd. Nigdy nie próbuj tego robić. Teraz mysql nawet nie zostanie poprawnie zainstalowany. Próbowałem ponownie zainstalować zależności:
sudo apt-get install --reinstall $(apt-cache depends mysql-server | grep -Po 'Depends:\s+\K[^ ]+$' | tr '\n' ' ' )
I same pakiety:
sudo apt install mysql-workbench mysql-server --reinstall
Ale dostaję różnego rodzaju tajemnicze błędy, takie jak:
sudo apt-get install --reinstall mysql-server

Lub jeśli ponownie skonfiguruję

Czy apt nie może odzyskać systemu po częściowej instalacji? Czy muszę ponownie instalować system operacyjny?
sudo apt-get install --reinstall mysql
