dpkg: error processing package mysql-server

Question

When I try to install mysql-server, an error comes like:

dpkg: error processing package mysql-server (--configure):
dependency problems - leaving unconfigure         


        

Answer 1

I tried almost every possible way but nothing was working for me. Then I found the problem that I was facing was due to less available ram. You can check your current ram status by free -h (in my case available was less than 1 GB). To clear ram restart your device. Then type following commands

sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade

then again install mysql-server by

sudo apt-get install mysql-server

Answer 2

The problem can be much simpler (in my case) I had a missconfigured value in my configuration file [my.cnf] which lead to the error. After cleaning up my.cnf mysql-server was restarted successfully

Answer 3

If you are working on Debian 10, you need to first install GNUPG:

sudo apt-get install gnupg

That's all; now you can try dpkg again.

Answer 4

I had a similar issue. This is how I fixed mine.

1. Restart MySQL service sudo service mysql restart
2. Then fix broken installations sudo apt install -f

Answer 5

try this solution using aptitude this will replace all the file corrupted.

This is work on my 18.04

Answer 6

My answer from askubuntu.

None of the apt methods worked for me, try this:

Find locking process

$ ps -eaf
root      7316     1  0 00:19 ?        00:00:00 /usr/bin/dpkg --status-fd 35 --configure --pending
root      7808  7316  0 00:19 ?        00:00:00 /usr/bin/perl -w /usr/share/debconf/frontend /var/lib/dpkg/info/mysql-se
root      7817  7808  0 00:19 ?        00:00:00 /bin/bash /var/lib/dpkg/info/mysql-server-5.7.postinst configure
mysql     7973  7817  0 00:20 ?        00:00:00 mysqld --user=mysql --init-file=/var/lib/mysql-files/tmp.iNyY06ty0K --so

Kill it

do sudo kill -9 7973, basically the mysql one.

Now purge

sudo apt-get purge mysql-server-5.7 # Or whatever you are trying to purge.
