6.1.y build fails to parse

[gregkh]

I don't know if we want to care about this version, but it fails instantly when trying to parse the output:

With latest branch, it's a different error:

I added a kernel build based on 6.1.y using localmodconfig on an Ubuntu25.04 system to our test cases.
However, I was not able to reproduce your issue. For this configuration the script did not fail as can be seen in this workflow run.

Can you provide the config that you used ? Then I could explore this issue further.

The config I use can be found here:

Ah nice thank you! :)

[augelu-tng]

This should work now.
Tested it for 6.1.y
