Hi Henry,
here from your logs:

2017-08-19T02:34:03.788619Z 0 [Note] Server hostname (bind-address): '127.0.0.1'; port: 3306

2017-08-19T02:34:03.788671Z 0 [ERROR] Do you already have another mysqld server running on port: 3306 ?
2017-08-19T02:34:03.788687Z 0 [ERROR] Aborting

So it seems you have (another mysql) service running on that port which makes install/upgrade of the package fail as they have to (re-)start the service.
Please check what is running on that port already and resolve that conflict - this should get you going again.

A way to check for that might be:
$ netstat -eeapn | less

And in there look for the 3306
