I found this same issue other people are facing, I tried their solutions, unfortunately nothing worked.
If I try service mysql start I get this error
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
When I run this /etc/init.d/mysql start
I get
Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details. failed!
What is the solution? I have 5gb space left out of 25 so space seems available.
Thank you
