Problem installing mysql on ubuntu?

Question

linux

Hello fellow toasters!!
There was a problem when trying to (re)start mysql on ubuntu.
Tried several commands such as:

sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean

and for reinstallation:

sudo apt-get update
sudo apt-get install mysql-server
sudo mysql_install_db
sudo /usr/bin/mysql_secure_installation

the output is an error

E: Could not get lock /var/lib/dpkg/lock - open
(11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/),
is another process using it ?

I try to delete it
sudo rm /var/lib/dpkg/lock
but I still get this error.
How to fix this situation?

Answer 1

sudo killall dpkg
or
ps -ax |grep dpkg
will show PID
kill -9 PID
