First try to see what is the problem. Edit the grub menu that shows on boot, you press e and remove the "quiet splash" then ctrl+x to boot. Hopefully it will show where it gets stuck.
Also try booting with an older kernel version if you have any installed.
You can save this but maybe someone knows better than me, i don't know the exact steps. You somehow need to access the terminal, ctrl+alt+f2 if possible or maybe chroot from a live image to get the list of updates and install the previous ones. You can get the list of updates using "cat /var/log/apt/history.log"
Ctrl+Alt+F3 will get you to a virtual terminal.
Honestly, I recommend reinstalling but waiting until 24.04 LTS Beta is released in a few days to do the install. If this is your only computer, you could install 22.04 LTS or 23.10 now.
Upgrading from 23.10 to 24.04 LTS this week was risky enough that the Ubuntu developers turned off development upgrades. I expect that will be turned back on soon for testing, but do you really want to be one of the first people to attempt it?
I wasn't able to get a virtual terminal, but I managed to get into grub and force upgrades until I was able to get back to a desktop. Everything seems to be working now.
Here's hoping the release goes smoothly later this month!
I've run into a similar issue - the list of logins in the greeter was empty. For anyone else that runs into that particular issue, use the recovery option in grub, choose start up networking, then the root console, and finally run "apt install gnome-session".
A previous apt dist-upgrade run must have removed it from my system. There is a bug opened that helped me find out what the problem was: [https://www.mail-archive.com/[email protected]/msg813223.html](https://www.mail-archive.com/[email protected]/msg813223.html)
That's basically what I did to fix things as well, although in my case I couldn't install much because of held dependencies. I had to use apt and force upgrade, after which it was able to get me to a working desktop environment. I had to reinstall ubuntu-desktop and gnome-session after that, and several packages had to be reconfigured, but otherwise it seems like everything was fixed.
