sudo dpkg --configure -a if doesn't work then
sudo apt-get autoremove mysql-server sudo apt-get autoclean sudo apt-get update sudo apt-get install --reinstall mysql-server
If it doesn't work then remove sources.list file.and create new sources.list...
sudo rm /etc/apt/sources.list
Then, type in
Then change the server to US or to any other server of your choice. You must enable repositories from the new dialog in order to create new sources.list.
Tick all the boxes then click on Revert then click close.
Need to restore default repositories
sudo apt-get update && sudo apt-get dist-upgrade -y
(it is good practice to backup this file before installing to recover if such things happen)
