I should definitly retry with debug logging… b.) guestfs works on jenkins.d.n which is the same hardware (kvm…) and the same software (jessie) -- cheers, Holger signature.asc Description: Digital signature ___ Reproducible-builds mailing list Reproducible-builds@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/reproducible-builds

And reading the code suggest that it should do (it's catching RuntimeError and returning back safely), but it is doing that only in open_archive, not in e.g. close_archive which seems to be where the actual crash is: > Traceback (most recent call last): > File "/usr/lib/python3/dist-packages/diffoscope/comparators/utils.py", line > 279, in __del__ > self.close_archive() > File "/usr/lib/python3/dist-packages/diffoscope/comparators/fsimage.py", > line 56, in close_archive > self.g.umount_all() > File "/usr/lib/python3/dist-packages/guestfs.py", line 9543, in umount_all > r = libguestfsmod.umount_all (self._o) > RuntimeError: umount_all: call launch before using this function > (in guestfish, don't forget to use the 'run' command) > Exception ignored in: > > Traceback (most recent call last): > File "/usr/lib/python3/dist-packages/diffoscope/comparators/utils.py", line > 279, in __del__ > self.close_archive() > File "/usr/lib/python3/dist-packages/diffoscope/comparators/fsimage.py", > line 56, in close_archive > self.g.umount_all() > File "/usr/lib/python3/dist-packages/guestfs.py", line 9543, in umount_all > r = libguestfsmod.umount_all (self._o) > RuntimeError: umount_all: call launch before using this function > (in guestfish, don't forget to use the 'run' command) > Am I missing some dependencies or what does that mean and what should I do > now?

Since guestfs works by running a modified kernel in an VM to parse the file system, I think it fails to start the VM (nested virt disabled, OOM, ...). So I think you should first try if guestfs works at all (without diffoscope) and/or enable the debug loggin like suggested in the error message. signature.asc Description: OpenPGP digital signature ___ Reproducible-builds mailing list Reproducible-builds@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/reproducible-builds
