Depois de atualizar para o Ubuntu 16.04, notei que o mysql estava tendo erros incompreensíveis. Convencido, era uma configuração quebrada, tentei executar uma limpeza do mysql. Isso não pareceu excluir tudo, então tentei fazer isso sozinho:
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
Isso foi um erro. NUNCA tente fazer isso. Agora o mysql não será instalado corretamente. Eu tentei reinstalar as dependências:
sudo apt-get install --reinstall $(apt-cache depends mysql-server | grep -Po 'Depends:\s+\K[^ ]+$' | tr '\n' ' ' )
E os próprios pacotes:
sudo apt install mysql-workbench mysql-server --reinstall
Mas eu recebo todos os tipos de erros enigmáticos, como:
sudo apt-get install --reinstall mysql-server

O apt não pode se recuperar de uma instalação parcial? Preciso reinstalar o sistema operacional?
sudo apt-get install --reinstall mysql
