If your case is just forgot password see then doc here .
Or remove mysql then reinstall may solve your problem.
Remove mysql:
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
Reinstall:
sudo apt-get update
sudo apt-get install mysql-server
sudo mysql_install_db
sudo /usr/bin/mysql_secure_installation
And just check your disk isn't full.

I see this when I ssh to my Ubuntu server:
Welcome to Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-1018-aws x86_64)
After installing mysql, I try to login to the mysql server but for some reason it asks me for a password that I do not have. So, I ran the following commands to uninstall mysql and reinstall.
Uninstall
sudo apt-get remove --purge mysql*
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get remove dbconfig-mysql
sudo apt-get dist-upgrade
The I used this link as guide to install mysql, and the commands went as follows:
sudo apt update
sudo apt install mysql-server
sudo systemctl start mysql.service
When I run:
sudo mysql_secure_installation
The prompt asks me to “Enter password for the user root”. Where do I find this password?
The idea of the command is to set the password.
How can I install mysql in this server to then be able to manage my databases?
I had many issues with MySQL software, even after uninstalling the files ten times, I still have it in my machine.
I want to remove everything because I have issues when I re-installing it.
The picture below is a screenshot after uninstalling all the MySQL packages.
I tried these commands :
sudo apt remove --purge mysql-server
sudo apt purge mysql-server
sudo apt autoremove
sudo apt autoclean
sudo apt remove dbconfig-mysql
These steps helped me.
sudo apt autoremove --purge mysql\* mariadb\*
sudo apt clean
sudo mv /var/lib/mysql /var/lib/mysql_bak
sudo mv /etc/mysql /etc/mysql_bak
Done.
I want to remove mysql with all data and reinstall it back. After uninstall and new installation all users are the same. Can i remove it and wipe all users, to have only one new root user?
sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
sudo apt-get autoremove -y
sudo apt-get autoclean
sudo rm -rf /etc/mysql
sudo rm -rf /etc/mysql /var/lib/mysql
apt-get --purge remove "mysql*"
This helped me.
I have a Mysql installation I'd like to remove and reinstall, running Ubuntu 14.04 on a LAMP stack. The passwords are all messed up, phpmyadmin isn't installing correctly... I just want a restart.
the command..
sudo apt-get --purge remove mysql-server mysql-common mysql-client
is returning the following error...
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I'm having a real hard time trying to figure out what to do with this.
this command...
sudo dpkg-reconfigure mysql-server-14.14
tells me...
package 'mysql-server-14.14' is not installed and no information is available
While..
mysql --version
tells me...
mysql Ver 14.14 Distrib 5.5.40, for debian-linux-gnu (x86_64) using readline 6.3
Any ideas how i can wipe this clean and restart?
thank you.
First, remove already installed mysql-server using-- sudo apt-get remove --purge mysql-server mysql-client mysql-common
Then clean all files sudo apt-get autoremove
Then install mysql-server -- sudo apt-get install -f mysql-server
Start mysql server-- sudo systemctl start mysql
Check status of mysql-server-- systemctl status mysql
Maybe strip the --?
sudo apt-get purge mysql-server mysql-common mysql-client
sudo apt-get install mysql-client mysql-server mysql-common
try to do this:
sudo apt-get install aptitude
sudo aptitude purge mysql-server mysql-common mysql-client
sudo aptitude install mysql-client mysql-server mysql-common
I was trying to install mysql in ubuntu. I applied following command for it
sudo apt-get install mysql-server-5.5
But got the following error.
Errors were encountered while processing:
/var/cache/apt/archives/mysql-server-5.5_5.5.41-0ubuntu0.14.04.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
Please help me to solve the error.
Doing this solved it for me:
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-5.5 mysql-server-core-5.5
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server
seems like there's an error with one of the packages being installed or that quite never installed properly in the past.
