Installer stuck in a loop while trying to add CD-ROM partition to apt sources

[merajmasuk]

What Happened?

I had to urgently clean install Pop OS LTS 22.04 on my machine and I had no working USB drive at my hand. Hence, I resorted to mounting the ISO file and copying everything to a 10 GB partition created on my hard drive. Then I booted the live media from there (Which now mounted at /cdrom/). During installation process the progress is gets stuck at 35%. Upon investigation I found that the installer was trying to add the /cdrom/ to the apt resources. But due to reading the name as '', it is giving error and stuck in an infinite loop. The partition had a name still the installer was giving the error (check logs).

Steps to Reproduce

1. Mount an iso image on CDROM
2. Copy the files from the CDROM on a separate partition (with name 'bootable' in my case) from the hard drive
3. Restart the machine and boot from that partition.
4. Proceed installation normally.
5. During installation it gets stuck at 35%.

Expected Behavior

It should proceed the installation normally without any error.
