I have installed Ubuntu 21.04 on my Laptop, everything with the DE was fine till now. I saw a video on YouTube showing the new Gnome 41. I wanted to install that. I didn't found a tutorial to install that one but I found one for Gnome 40. So I thought I could install that and then upgrade it. After following this Tutorial, my system corrupted. That means that when I start it up, it only shows a sad emoji with the text Oh no! Something went wrong. A problem has occurred and the system can't recover. Please contact a system administrator. This happened after I typed

sudo add-apt-repository ppa:shemgp/gnome-40

and pressed enter to install it and then installed gnome-session like it recommended it in the page that the above command showed like this:

sudo apt install gnome-session -y

after that I Logged out and got that screen like I described earlier. I am able to go into my console by pressing Ctrl+Alt+F5 and then I tried uninstalling the gnome-session thing with:

sudo apt remove gnome-session

I also tried to to remove the repository, but there it was just more trial in error:

sudo apt-add-repository -r ppa:shemgp/gnome-40

I don't even know if this command existr like that Hope you can help me ASAP and if you need more info, just say it. I could also share the command history if you want to. Output of

grep -ir MasterSoft24 /etc/apt --include="*.list"

/etc/apt/sources.list.d/home:MasterSoft24.list:deb http://download.opensuse.org/repositories/home:/MasterSoft24/xUbuntu_20.10/ /

Removing repository with sudo apt-add-repository -r ppa:shemgp/gnome-40 will not downgrade the packages to their stock versions.

You have to use ppa-purge instead.

So you have to re-add the problematic PPA by

sudo apt-add-repository ppa:shemgp/gnome-40

then install ppa-purge by

sudo apt-get install ppa-purge

and finally revert all GNOME packages to their official versions using

sudo ppa-purge ppa:shemgp/gnome-40

Then reboot.

When I do this I get the Error W:GPG error: <link> InRelease: The following signatures were invalid: EXPKEYSIG 54E795FB12ECE9A9 home:MasterSoft24 OBS Project E:The repository <link> In Release is not signed Warning apt-get update failed for some reason But I also tried to install gnome-session again in the meantime, which said that it needs older versions of gnome-session-bin and common, from which I looked up the version with apt-cache and removed the versions 40.1.1-0ubuntu3 and then reinstalled gnome-session. Maybe that's why it's still not working btw I don't get the Error Screen now

You have to correct your repositories and GPG keys. The downgrade process can't be run when they are broken. Please add output of `grep -ir MasterSoft24 /etc/apt --include="*.list"` to the question.

Or try to run `wget -q https://download.opensuse.org/repositories/home:MasterSoft24/xUbuntu_20.10/Release.key -O- | sudo apt-key add -` directly. Then run `sudo apt-get update` and ensure that you do not have errors anymore.

I still got the errors after doing the wget command. But while doing the wget command I got the Error: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

This is a warning. Please be more accurate. Please upload full output of `sudo apt-get update` to the pastebin.

You have to remove MasterSoft24 repository's *.list file and then retry.

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.
