password containing special characters not working when logging in after installation

[Christian W]

Passwords containing special characters entered during installation are not working for 1st login.

I tried it 2x and have verified visually that I entered the pw correctly. It contains chars such as '#' 'ä' '+' '<'

3rd attempt with "12345" worked.

Shall we take a guess at what you're installing?

[Christian W (chrisler)]

Ubuntu 24.04 LTS installation from website image via USB drive.
i5 gen 3 CPU.

Thank you for your bug report. Which language and keyboard layout are you using? Would it be that the wrong layout is active on first boot? If so it could be something similar to bug #2063230

[Christian W (chrisler)]

The installer was in German and I used a German Keyboard layout (QWERTZ). During the second installation attempt I've double checked that the clear text pws entered during the installation and first login were 100% identical. I had also tried to login from emergency console (e.g. ctrl+alt+F3) without success. At first I thought that a different keyboard setting at login could be the problem, but only German layout was available, as expected. So I don't think it is the same problem as #2063230.

Weird, if login also fail from a VT then it's probably a subiquity / cloud-init problem. Is it working after a restart then? Can you check the journalctl log from the first start and attach it to the bug?

[Christian W (chrisler)]

I didn't try to restart but went straight for another installation attempt from the usb live system. So I can only offer you a journalctl log from the first boot with pw "12345", attached.

Several things went wrong last Sunday, including a corrupted file system on my external backup drive...
So I had to filter the ntfs file system errors from the journalctl log with "grep -v 'ntfs-3g'" - the file was 3.9 GB! If anything is missing, just let me know, I'll delete the logs next week.

Cheers,
Chris
