Description Larry O'Leary 2021-05-03 22:52:04 UTC
Description of problem:
Unfortunately I am not certain what is actually failing as I am not able to find any details about what is happening or where the error is actually originating.

When attempting to build live media using livemedia-creator I receive the error: "Problem reading label from /home/me/ks/Fedora-Server-netinst-x86_64-34-1.2.iso: Invalid APM signature"

I have attempted this with the Everything ISO with identical results. 

Version-Release number of selected component (if applicable):
Name         : lorax
Version      : 34.9
Release      : 5.fc34
Architecture : x86_64

How reproducible:

Steps to Reproduce:
1. sudo livemedia-creator --make-iso --iso=Fedora-Server-netinst-x86_64-34-1.2.iso --ks=/usr/share/spin-kickstarts/fedora-live-workstation.ks

Actual results:
livemedia-creator terminates early with a final message of "'NoneType' object is not iterable". Note that this appears to be due to "Problem reading label from /home/me/ks/Fedora-Server-netinst-x86_64-34-1.2.iso: Invalid APM signature"

Expected results:
Live media ISO is created.

Additional info:
Here is the output of the command:

Comment 1 Brian Lane 2021-05-04 15:38:04 UTC
Have you confirmed that the checksum of the iso matches what is expected? eg. https://dl.fedoraproject.org/pub/fedora/linux/releases/34/Server/x86_64/iso/Fedora-Server-34-1.2-x86_64-CHECKSUM

I've never seen 'APM signature' mentioned anywhere, and web searches aren't helping...

Can you attach the program.log file? It may have more details about what failed. Also check the system's logs with journalctl -e right after it fails to see if anything is logged.

I suspect it's just a corrupt iso file.

I have tried multiple ISOs and verified their checksums. I have also tried this on Fedora 33 and Fedora 34. I have also verified that the ISOs are mountable and bootable. This error only seems to be an issue when running livemedia-creator. I have also tried from two different machines so the problem seems consistent.

These specific logs were generated in my attempt to use mock but I have also tried without mock and using the Fedora 34 workstation kickstart file directly with identical results.

Comment 5 Larry O'Leary 2021-05-04 17:12:51 UTC
No error or warnings from journal during execution. Here are all three correlated logs. Note the livemedia-creator error was captured at 2021-05-04 12:03:44,979:

Comment 6 Brian Lane 2021-05-04 22:14:53 UTC
I am unable to reproduce this with Fedora 33 and either the F34 or F33 isos, I am also unable to find any reference to what APM signature is.
Is there something special about your system?

Comment 7 Brian Lane 2021-05-05 17:03:47 UTC
Ok, I've figured this out. It's a bug in pycdlib that has been fixed in git and needs to be ported to the Fedora package.
