I was repeatedly having prompts to update Brave Browser, despite following the prompt and updating the browser, and I saw that it was from the "snap store", so I uninstalled and reinstalled snapd.I uninstalled and reinstalled Brave Browser, but now the Brave Browser would try to start, but wouldn't start.
I try to start Brave Browser from the CLI, and this is what happens:
el_gallo_azul@desktop-ubuntu:~$ brave
Command 'brave' not found, but can be installed with:
sudo snap install brave
el_gallo_azul@desktop-ubuntu:~S sudo snap tnstall brave
[sudo] password for el_gallo_azul:
error: cannot perform the following tasks:
Run configure hook of "brave" snap if present (run hook "configure": cannot locate base snap core22: No such file or directory)
el_gallo_azul@desktop-ubuntu:~$ standard-notes
cannot locate base snap core22: No such file or directory
el_gallo_azul@desktop-ubuntu:~$ sudo snap install core22
snap "core22" is already installed, see 'snap help refresh'
I just ran through the same thing with Mozilla Firefox browser, in an attempt to paste the CLI text into this AskUbuntu question, but it wouldn't start. A similar problem occurred when I tried to start it from the CLI, and again when I tried to install it (although it was already installed).
I then tried to use the Standard Notes app as a place to store this CLI text, so I could transfer it across OSs and paste it into AskUbuntu, but the Standard Notes application wouldn't start, either.
I just tried again, and there was something about core22 missing, which I then installed, but it did not make any difference.
I am not able to use Ubuntu 22.04. I am only able to use Tails 6.4 for now.
Edit 20240630: As requested, I add the following.
I haven't been able to use Ubuntu for a few weeks now, so when I booted into it, the first thing I did was a big, fat update, which included kernel image and a load of 'snap' updates. I mistakenly got my hopes up. Then I did the following.
$ brave
Command brave' not found, but can be installed with:
sudo snap install brave
$ sudo snap install brave
[sudo] password for el_gallo_azul:
error: cannot perform the following tasks:
Run configure hook of "brave" snap if present (run hook "configure": cannot locate base snap core22: No such file or directory)
$ sudo snap refresh
error: cannot perform the following tasks:
Run post-refresh hook of "firefox" snap if present (run hook "post-refresh": cannot locate base snap core22: No such file or directory)
Edit 20240704 I add the following after following more suggestions in the comments. I hope I have corrected all the OCR errors.

And lastly, snap list.I was not able to extract the text in columns, so I attach the corresponding image:

This was what worked for me, as suggested by @Lety, who deserves the bounty.
