Do we need to worry about upgrading Debian 10?

Yes, I’am. From 10 to 11. In-place.
Here is my observations. Of course, I had backups made.
And next weekend I will probably go from 11 to 12. In-place .

The another problem occurred with the Virtualmin installation. Apt offered me autoremove for bind, mariadb, postfix and many other packages that Virtualmin depends on. So the dependency chain was broken somewhere. How to fix it? With Apt reinstall Virtualmin? Or? It would be convenient to treat this with some Post-Invoke script. It could happen that someone will use the offered autoremove.

This is not true, but I didn’t realize that at the time. Only packages from version 10 were offered for “apt autoremove”.
