What does ufw logging do?
Firewall logging.
Var being 2GB still sounds pretty big.
Let's look at the Terminal output of

Code: Select all

That appears to have done it. /var is now 1.0GB.

Those should be self maintaining I don't know what happened in your original problem. Keep an eye on it to see how it goes. Think about doing Mint 20 when it's released - probably by early July or so.

OK but, I've got another problem. After my thank you, I made another Timeshift snapshot and then shutdown. When I came back to it, I was unable to login. The system boots to the login screen and I can put in my password but, after clicking enter the screen blinks and then it is back to the login screen. I doubt that it is related to anything we've done. I guess I need to open a new thread. Timeshift is now set to put snapshots on an external drive. Doubt that that is related. I'm writing this from Windows on the same machine. So, not a total system problem.

You need to recover with a live session of Mint. Attach your snapshot drive and boot to live. Once booted, launch Timeshift. Go to its settings>location>and locate your portable drive's snapshots. While in settings, go to users tab and put the dot to include all (that's ok for you because of how you configured the snapshots) Select the snapshot you made when mint it was working. Then click Restore. Leave the choices at default and follow the prompts until it's recovered. Close everything and shutdown. See if it's ok. You know you can install Mint 20 Beta and upgrade it to the stable release when that option is in the Update Manager very easily. Might be worth considering.

I did the Timeshift restore and it worked great. After, I was able to log in with no problem and everything looks like it was before shutdown.
Thanks again.
