Updated to 249-11-0ubuntu3.6 using normal repository.
The error " mtd device must be supplied (device name is empty)" disappeared.
[actually with normal sudo apt upgrade nothing was being upgraded saying "The following packages have been kept back: <packages etc etc includingsystemd>. Solution 2 here did the job https://askubuntu.com/questions/601/the-following-packages-have-been-kept-back-why-and-how-do-i-solve-it ]
Yet, I am left with an emergency terminal and no graphical interface.
I can log in and use this minimal terminal.
I will open another thread, as the initial bug seems not related to the major breakdown of the whole graphical interface.
*UPDATE* I found that, in my case (may absolutely be not reproducible), the whole gdm3 (gnome graphical engine) graphical interface was missing.
A simple "sudo apt install gmd3" fixed the issue and gave me back the graphical interface.
My best guess so far is that I closed the lid of my laptop exactly while the gdm3 was being upgraded (during a normal daily update/upgrade), so the old version was already removed but the new one not installed yet.
So not really a bug, but a failure on the human side.
