MySQL server was running fine last night, but this morning, when I tried to hit the Bugzilla server, I found it down. I tried to start it, but I get:

Job for mysql.service failed because the control process exited with 
error code. See "systemctl status mysql.service" and "journalctl -xe" for 
details.

I have done a few google searches and found a bunch of questions. I tried some of the answers, but the server is still down. I have plenty of space,

root@GBRTEF01LX005:/home/bzadmin# df -h

I have also added more swap space for InnoDB,

innodb_buffer_pool_size = 20M

which is one of the suggestion I found, and lastly, here is the last 30 lines of journalctl -xe,

root@GBRTEF01LX005:/home/bzadmin# journalctl -xe | tail -30

After an import of another database, the mysql root@localhost was not taking. I know that it worked because the data got imported and I was able to change the password of the user that was imported using root. However, after a day running, I tried to login as root and I couldn't. I tried a bunch of other web suggestions, etc., but none worked. I was running mysql-server-5.7. Anyway, since I knew that I just needed to recover the data, I said let me reinstall it and I would be on my way. WEll, I was wrong. For some reason, I was not able to uninstall it, nor install it back. Finding a few web suggestions, I am now at this state where when I type,

apt-get install mysql-server

I get.

root@GBRTEF01LX005:/home/bzadmin# apt-get install mysql-server
Reading package lists... Done

E: Unable to locate package mysql-server

Any other suggestions? Thanks.
