Hey Geoff,
It sounds like you're dual booting two copies of Ubuntu then which is 
very strange... unless you were upgrading from 18.04 to 22.04 and got 
half way through (perhaps leaving old and new entries in the GRUB menu, 
which I presume you're referring to - that's the menu that appears 
before either Ubuntu starts).
If you've got something like GParted installed then it might be worth 
sending over a pic (it'll show a diagram when opened) of what that looks 
like to be sure (by confirming how many partitions/filesystems you have, 
and of what type... it'd rule out if you're dual booting or not).
Do you remember trying an upgrade from 18.04 to anything newer?
Also, we've been going since 1999... so trust me when I say we have 
people on this list from ALL ages!
Helping out fellow Linux users is a core part of what a LUG should be 
about in my opinion, it certainly was when they were thought up back in 
the 90's.

 Hello Steven
 Thank you for your reply.
 You are right it is 18.04 and also for some reason I also have 22.04 
 options. I am unable to upgrade from 22.04, and 18.04 is a 
 separate version that I can open which shows files from that release. 
 Confusing. However, and weirdly I have been able to boot both, 
 separately.
 I have done what you have suggested and got a response that my 
 Nividia module is not configured correctly. So I am going to explore 
 how I can deal with it.
 Finally 2 points, to add to our conversation. Time to get your 
 handkerchief out. I am 73, and I find this very difficult to 
 understand and also please do tell me if I am a nuisance, I 
 genuinely wont be offended.
 Kind regards
 Geoff

     Hey Geoff,
     I'm guessing this is perhaps Ubuntu 18.04 or higher?  And perhaps
     you started to get this crash shortly after updating your kernel
     and/or graphics drivers/card?
     Basically that last thing in the boot sequence (the 'GNOME Display
     Manager', or GDM) is the thing that starts up X.org (which is the
     process that runs the graphical environment)... and since you can
     still see text, that must not be working.
     I'd advice rebooting into recovery mode and from the recovery menu
     there might be an option for something like 'failsafeX' or
     something like that... so that you can get back into the graphical
     environment with a safe low-end graphics mode to fix things.
     Probably a DKMS module (e.g. if you use NVIDIA or AMD graphics)
     didn't get re-installed from your last kernel upgrade.
     Let us know if how you get on, but that should point you in the
     right direction.
     Also from your postcode, you'll probably find WolvesLUG more local
     if you need to reach out to someone who lives near by (we're happy
     to have you here too :P)
     p.s. With you mentioning pubkey errors... that's likely (at a
     guess) something you're seeing with APT (or something that calls
     it, like whichever program you install software using) and
     probably just means you need to update your repo's... but it's
     probably not related to this issue.
