This is a failure of run-debuginfod-find.sh only on this particular
worker which identifies as:

Fedora release 30 (Thirty)
Linux 5.2.9-200.fc30.ppc64le #1 SMP Fri Aug 16 21:03:00 UTC 2019
GNU C Library (GNU libc) stable release version 2.29.
g++ 9.1.1
binutils 2.31.1

configured with:
./configure --enable-maintainer-mode --enable-sanitize-undefined --
disable-valgrind

I have not been able to replicate the failure on the exact same setup.

The end of the log looks like:

Anyone a guess what is going on in this case?

Thanks,
