Recently after a backup restore MySql server failed to start with the following error message:
start: Job failed to start
To fix start: Job failed to start I had to re-install the MySQL server.
I hope you have a backup of your data because you will lose all your MySQL data running the following commands
After boot there was no console prompt to login.
The issue was related to the VGA resolution.
To fix Ubuntu server no login console
modify in /etc/default/grub
# Grub Resolution
# Kernel param to set a port to resolution and vertical refresh.
Of course, you can set resolution to suit your needs by replacing 1024x768x24 to whatever you need.
