Ubuntu 21.04 Black screen at login screen after system update

cn flag

After the last Ubuntu update black screen at login (Mouse pointer is visible).

I am getting 'Oh no! Something went wrong' screen on startx command:

Oh no! Something went wrong screen

I have tried update & dist-upgrade, tried to reinstall ubuntu-gnome-desktop, but broken packages error.

The following packages have unmet dependencies:
 gnome-shell : Depends: gnome-shell-common (= 40.2-0shemgpubuntu2) but 40.3-0shemgpubuntu2 is to be installed
E: Unable to correct problems, you have held broken packages.

But no hold packages are there

$ sudo dpkg --get-selections | grep hold
$ sudo dpkg --configure -a
$ sudo apt-get -f install

Gnome 40 was installed via ppa

I have un-commented the following line in the sources list /etc/apt/sources.list.d/shemgp-ubuntu-gnome-40-hirsute.list

deb http://ppa.launchpad.net/shemgp/gnome-40/ubuntu/ hirsute main

After this everything is working properly. Following commands fixed my issue

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-gnome-desktop --reinstall

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.
