Execute os seguintes comandos:
mkdir MYSQL
cd MYSQL
sudo apt-get download mysql-common
ar xvf mysql*
tar xvf dat*
sudo cp ./etc/mysql/my.cnf.fallback /etc/mysql/my.cnf.fallback
sudo dpkg -i mysql*deb
cd
sudo apt-get -f install
Eu atualizei o sistema alguns dias atrás e depois disso tive um problema de pacotes quebrados que afeta o MySQL e várias bibliotecas. Depois disso, posso fazer atualizações, mas não instalo, atualizo, removo ou purga pacotes, e não encontro nenhuma maneira de resolver o problema de dependências quebradas.
Eu não tenho certeza se o problema das dependências quebradas e do MySQL estão diretamente relacionados ou não, então tentarei descrever os dois separadamente.
Primeiro, se eu tentar instalar um pacote ou fazer uma atualização, recebo a seguinte mensagem:
$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libsasl2-modules:i386 : Depends: libssl1.0.0:i386 (>= 1.0.0) but it is not installed
skype-bin:i386 : Depends: libssl1.0.0:i386 but it is not installed
E: Unmet dependencies. Try using -f.
Se eu usar a opção -f de atualização, obtenho
$ sudo apt-get -f upgrade

Olhando com o Synaptic, vejo os seguintes pacotes quebrados
libsasl2-modules;i386
skype-bin:i386
Aqui, se eu tentar remover, reinstalar ou qualquer coisa que eu receba com o Synaptic, sempre a mesma mensagem de erro

Se eu tentar configurar o MySQL (o que é instalado teoricamente na versão mais recente), então recebo esta mensagem:

Na atualização do MySQL, algo foi realmente estranho.
Por exemplo, procurando pelos arquivos my.cnf , my.cnf.fallback etc ... eu percebi que os arquivos e suas pastas não existem mais. Eu ignoro como eles desaparecem durante a atualização. p>
Tentando reinstalar o MySQL sem qualquer esperança, recebi esta mensagem:
$ sudo apt-get -f install mysql-common

mysql-common is already the newest version (5.7.12-0ubuntu1.1).
You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Se eu usar a remoção para desinstalá-los e começar do zero, terei os mesmos problemas

Alguém tem uma ideia, o que eu posso fazer?
Execute os seguintes comandos:
