Login issue after upgrade above linux-5.15.5-artix1-1

After updating the system above linux-5.15.5-artix1-1 I can not log in. After entering the username and password, the same window appear. Initially, the system was set to enter without requiring a login and password. But after the update, this request appears.

You should boot into a live session and mount your system to query more information about what is going on in your logs

Search for authentication issues

As I understand it, I have to search in this folder "/var/log". But in which file and which line should I pay attention to? There are a lot of files: auth.log , errors.log , messages.log , everything.log , and others

How about:
Code: [Select]
$ grep -E '(auth|login)' /var/log/* 2>/dev/null | less
or even
Code: [Select]
$ grep -E '(auth|login)' /var/log/* 2>/dev/null >interesting.log.lines
then you get those lines neatly in a file.

Thanks, this makes searching much faster.

For now I have found these suspicious lines. I tried to login three times.

This looks like a log from live environment's /var/log. If your user was named "artix", disregard the rest of this paragraph. Otherwise, please upload the corresponding logs from your hard disk. You can do that by mounting the root partition (or the partition holding the /var/log on the hard disk) to /mnt in the live environment, like described in the "Troubleshooting" article. Then find the logs under /mnt/var/log instead of /var/log.

Update: Looking at errors.log, this looks suspicious:

this is weird. For some reason (maybe related to disk errors above), a directory required for pulseaudio to function is missing. I'd check hard disk cables and hardware first.

1. That's right, user was named "artix"
2. dev sdb - it's a card reader. Didn't notice any problems with it.
3. The system is installed on Nvme and there are no problems before the update. Updated system after Jan 26 17:00.
Perhaps a pulseaudio bug is causing the login to fail after an update?

Are you sure? Devices could be assigned different pseudo-files under /dev; what is once represented by /dev/sda could under some circumstances be under /dev/sdb and vice versa. That's why it is recommended to use UUIDs in /etc/fstab instead of device filenames.

What is the output of
Code: [Select]
lsblk -f

It could be. You said you had autologin enabled in lightdm? What is the contents of /etc/lightdm/lightdm.conf? And the output of
Code: [Select]
groups artix
(if the user is named "artix").

If the issue is related to a pacman update, also supply part of /var/log/pacman.log around the date when you experienced the issue first.

Perhaps it would be faster to reinstall Linux? There will be no problems with installing the necessary programs, but the visual configuration of all panels, shortcuts and other things will take a lot of time. Is it possible to save all these settings with the possibility of transferring to a new system?
