In reply to Cliff Sloane. sorry, but why are you intend to upgrade LM 21 from LM 19.3????. As I understand the upgrademint tool works only for upgrades from LM 20.3.

I have found the answer to my question myself.

Open a terminal and punch in the following command: “sudo touch /etc/timeshift.json”

If you want to use Timeshift (again), you need to remove that file.

I tried it twice. In the second attempt I fixed the mistakes from the first (foreign PPAs). THe mintupdate check had no flags and it proceeded as described. When I rebooted, Cinnamon crashed, dozens of unmet dependencies (all seemingly related to python3), and none of the system windows (Control, Preferences, Update Manager, etc) would open. From CLI, apt did not work (missing apt_pkg module) and dpkg fixes failed.
I restored from timeshift via CLI.
I love 19.3 and I am happy to ignore the upgrade, unless the fix for this is known. Anybody?

I am quite new to Linux, so forgive me if this seems like a stupid question. I’d like to upgrade, but not having Timeshift seems to be a major issue. I do not want (to use) Timeshift, I have my own methods of securing my system for f@#k ups, or other “disasters”. Is there any way to bypass this Timeshift thing? Any help is greatly appreciated.

Hi – here’s what I did …
apt get remove libgirepository-1.0-1

Then I did the upgrade and it worked … with a good deal of anxiety. Removing this file really breaks Linux … a lot of stuff stops working. The upgrade, however, then worked flawlessly as does the computer now. I am not sure what would happen if you lost power or turned off the computer before upgrading … probably wouldn’t be pretty. Thankfully, I didn’t really know what I was doing when I did the uninstall. 🙂 (… and figured I could use TimeShift after booting to a USB stick if I really needed…)

Upgrading gave the error “breaks: python-gi (< 3.34.0-4~) but 3.26.1-2ubuntu1 is to be installed"
Resolved by running "sudo apt install python3-gi" which will install a later python-gi to overcome the error and will update other programs too. To finalise the install then run "sudo apt dist-upgrade" again and this time the upgrade process completed without error.

If you have another error then search how to install , carry out install and try upgrade again.

Some simple rules to avoid 90% problems in all debian based systems
1) Do not put packages on hold, unless you know what you are doing.
2) Unhold packages before big upgrades, unless you _really_ know what you are doing
3) Do not use apt-get from command line for any complicated things
4) Use aptitude, where you can preview changes and resolve broken dependencies, before applying them (synaptics can do this too, but it has awful UI)
And the most important one:
5) If you do not understand how package management system works and what dependencies are (and don`t want to learn), DO NOT follow ANY guides in the internets, including mine. Just do fresh install.

Painful… I don’t know what to do.
I get stuck in Fallback mode due to a cinnamon error and I can’t fix it.
