Cinnamon Fallback mode when upgrading to Mint 20

Post by xisvaldo »

Hello,
I'm new using Linux but I have this laptop with Mint 18.1 and due to my company requirements I must upgrade it to Mint 20. Everything was fine and I was able to upgrade until 19.3.
When I was upgrading from 19.3 to 20, I got an internet issue and wasn't able to complete the installation. I reboot my computer and for my surprise, it was showing Linux Mint 20 while booting.

But then I got lots of errors: shortcuts doesn't work (Ctrl + Alt + T, Windows Key and so), I got this Cinnamon Fallback mode error and something about MintMenuAppletFactory::MintMenuApplet error (which I deleted).
Some of services were deleted (such as mariaDb, Chrome...) and I guess I don't have a Timeshift backup (unless upgrading has created it automatically).

Here is my

The data you posted indicates you have a cross between LM19.3 and LM20. Usually, the fastest and best way to fix that is to back up all your personal data and do a fresh install of LM20.

Upgrading does not create a backup. That is a step which is recommended to be done, but it must be done manually.

The Cinnamon version listed here is the one for LM19. Notice there is one gcc version listed for System (which is the correct one for LM20, but the older version is listed in Info (the version used in LM19).

The graphics files look like the correct ones for LM20. I do not know how to help you fix this situation, but maybe someone else will if, for some reason, you are not able to do a fresh install.
