I did a system update today and now I have a couple of serious problems.

I use Thunderbird mail and today I have reminders that won’t go away. I 
tried dismiss and snooze and dismiss all, tried the X in the upper 
corner and close in the panel bar at the bottom of the screen. It closes 
and comes right back.

I also use Audicity and it’s giving me a debug report when I open the 
program. That is also new today after the update. When I click on the OK 
button, it clears the debug report and closes the program.

These are the only two programs I’ve used so far today, so I don’t know 
what else lurks in my system.

What I would like to do is undo the upgrade and redo the upgrades one 
item at a time.

I’ve looked online but can’t locate how to undo updates.

I am using Mint 18. My Update Manager is set to “Optimize stability and 
Security”. I am allowing level 1,2 and 3 updates only. My update 
preferences are set to default settings.

51 updates were installed today. My last update was 08/02.

Can anyone tell me how to undo todays update.

Any help will be greatly appreciated.
