Something has gone wrong even if the upgrade was successfully

There are tons of questions about this error but almost all of them refer to interrupted dist-upgrades. Instead, I've upgraded from 20.04 to 21.10 without any problem (at least, no popups that show errors).

The machine is headless and it's configured with a dummy monitor to be accessed by a remote desktop application:

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "dummy"
EndSection
Section "Monitor"
    Identifier  "Configured Monitor"
    HorizSync 31.5-48.5
    VertRefresh 50-70
EndSection
Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1920x1080"
    EndSubSection
EndSection

I have a sort of SSH connection to the device, but when I try to enable the remote desktop I get the "Something has gone wrong" screen.

I tried almost all the solutions provided in the other threads, example:

$ sudo apt-get upgrade && sudo apt-get update
$ sudo apt-get update && sudo apt-get dist-upgrade 
$ sudo apt-get upgrade
$ sudo apt full-upgrade
$ sudo apt --fix-broken install
$ sudo dpkg --configure -a
$ sudo apt-get remove gnome-session gdm3 gnome gnome-shell
$ sudo apt-get autoremove
$ sudo reboot

but none of them fixed the problem.

I checked dmesg output but I found only this error:

[   20.487647] gnome-shell[1144]: segfault at cc0800b8 ip 00007fea14214015 sp 00007ffe766e7cb0 error 4 in libxkbcommon-x11.so.0.0.0[7fea14213000+4000]

as I read somewhere it should be there because I disabled Wayland.

Any hint about what I can check?

*I've upgraded from 20.04 to 21.10 without any problem* How did you do that? There is no supported upgrade path.

I did it on three machines without any issue. The `update-manager` GUI told me there was a newer version available and asked me if I want to upgrade. Then it did the dist upgrade.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
