Решение проблем MySQL

При обновлении новой версии может происходить ошибка типа такой:

text

update-alternatives: error: no alternatives for my.cnf
dpkg: error processing package mysql-common (--purge):
 subprocess installed post-removal script returned error exit status 2
Errors were encountered while processing:
 mysql-common

или такой:

text

update-alternatives: error: /var/lib/dpkg/alternatives/my.cnf corrupt: invalid status
dpkg: error processing package mysql-common (--purge):
 subprocess installed post-removal script returned error exit status 2
Errors were encountered while processing:
 mysql-common
E: Sub-process /usr/bin/dpkg returned an error code (1)

или такой:

text

update-alternatives: error: unable to read link '/etc/alternatives/my.cnf': Invalid argument
dpkg: error processing package mysql-common (--configure):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 mysql-common
E: Sub-process /usr/bin/dpkg returned an error code (1)

Решается командой: sudo dpkg -P --force-all mysql-common

Если не помогло, то так:

bash

sudo rm /etc/alternatives/my.cnf
sudo ln -s /etc/mysql/mysql.cnf /etc/alternatives/my.cnf
