How can I resolve login issues after attempting to upgrade to Ubuntu 22.04.5 LTS?

So, I’ve been trying to upgrade my system to Ubuntu 22.04.5 LTS, and honestly, it’s been a bit of a rollercoaster ride. Everything seemed to be going smoothly at first—downloading the updates, going through the upgrade process, and all that jazz. But then came the part where I had to log in afterward, and that’s where I hit a wall.

When I attempt to log in, it just keeps taking me back to the login screen, like some sort of annoying game of tag. I’ve double-checked my username and password to make sure I’m not going crazy, and I’ve even tried the recovery mode to see if I could fix anything from there. I mean, I would expect that if things went wrong, recovery mode would be the silver bullet, right? But no luck. I tried to reset my password through the recovery mode options, yet I still can’t get in.

I don’t think it’s a hardware issue or anything since I’ve been running Ubuntu on this machine for a while now without any major hiccups. The last version was working perfectly fine, but this upgrade has turned into a nightmare. I’ve done some digging online and found a few threads where people have had similar login issues after the upgrade, but the solutions seem to be all over the place. Some suggest reinstalling the desktop environment, while others talk about checking for issues in the .Xauthority file or something like that. Honestly, some of it sounds like Greek to me.

I don’t want to end up doing a fresh install, as that feels like a last resort. Plus, I have some files and settings that I’d rather not lose. So, has anyone gone through this and managed to fix the login looping problem? I’d really appreciate any tips or guidance on what steps I could take next. Help me break this cycle of frustration and get back to enjoying my upgraded system!

    1. Stuck in Login Loop After Ubuntu Upgrade? Here’s What You Can Try!

      First off, it totally sucks to get stuck in a login loop after an upgrade! I feel your pain. Here are a few things you might wanna try to break that frustrating cycle:

      1. Check .Xauthority File

      Sometimes, the .Xauthority file can cause issues. Boot into recovery mode and try the following:

              cd /home/your_username
        ls -la

      If you see a .Xauthority file, you can rename it:

              mv .Xauthority .Xauthority.backup

      Then try logging in again!

      2. Reinstall Desktop Environment

      Sounds like some folks have had luck reinstalling their desktop environment. You could do this from a terminal:

              sudo apt-get install --reinstall ubuntu-desktop

      Just follow the prompts, and then reboot to see if that helps.

      3. Check Permissions

      Make sure your home directory has the right permissions. Run this in recovery mode:

              sudo chown your_username:your_username /home/your_username

      Replace your_username with your actual username. Then reboot!

      4. Look at Logs

      If you’re feeling adventurous, check the logs for clues. You can find them in:

              /var/log/syslog
        /var/log/auth.log

      Maybe something in there will give you a hint.

      5. Last Resort: Backup and Fresh Install

      If all else fails and you really can’t get in, consider backing up your important files using a live USB. Then, you can do a fresh install. I know, total bummer, but sometimes it’s the only way!

      Keep your chin up! Hopefully, one of these tips helps you get past that login loop and back into your system!

    2. Experiencing a login loop after an upgrade to Ubuntu 22.04.5 LTS can be frustrating, but there are several troubleshooting steps you can take before resorting to a fresh install. First, ensure that your system is up to date by accessing the recovery mode and entering a root shell. You can then try to reinstall the desktop environment using commands like sudo apt-get install --reinstall ubuntu-desktop or sudo apt-get install --reinstall gdm3 if you’re using Gnome. Additionally, check if there are any issues with your user configuration files, particularly .Xauthority and .ICEauthority. You can set proper ownership with chown yourusername:yourusername .Xauthority .ICEauthority, replacing yourusername with your actual username.

      If the above suggestions don’t resolve the issue, consider checking your display manager. Sometimes, the problem may arise from an incompatible display manager configuration. You can switch to a different display manager by running sudo dpkg-reconfigure gdm3 (or whichever display manager you prefer) and selecting another option. If you find yourself still in the login loop after all this, gathering logs from /var/log/syslog or /var/log/Xorg.0.log might provide insights into what’s going wrong. Remember, a backup of your important files is crucial before performing further troubleshooting steps, especially if things escalate. Community forums can also be a valuable resource to see if others have faced similar issues with particular hardware.
