I tried to update from 16.04 to 20.04, and as is customary, everything went to hell. The GUI was not launching at first, but I got through that by fixing broken packages and reinstalling the linux kernel.

I can now boot into Gnome desktop and use some programs. However, I get intermittent error messages - Sorry, Ubuntu 20.04 has experienced an internal error with a crash in gnome-control-center.

error

By the way, I tried to reinstall gnome using the following command, but still see errors above.

sudo apt install gnome-session gdm3

How do I reinstall the Gnome GUI portion of by Ubuntu 20.04?

As this has been viewed more than 10k times (!) and people still having problems; and still no (at least not "working") answer; If someone would have this problem again; check my answer on this thread

A snippet of it below note - please do read the post; as it contains info about not only the problem; but some other(likely to come after) problems with Gnome/Nvidia(for example)

sudo apt update
sudo apt upgrade
sudo apt autoremove

sudo apt remove ubuntu-desktop
sudo apt autoremove
sudo apt install ubuntu-desktop

or sudo apt-get install ubuntu-gnome-desktop

one could as well as try sudo apt-get install --reinstall ubuntu-gnome-desktop
