Hi,
I'm afraid this indicates there's corruption in the backup repository.
It looks like the chunk file is compressed, but the file has changed,
and can no longer be uncompressed. There's not really anything Obnam
can do about that.
If you can find out how the file got changed, I would be glad to know.
If it's a bug in Obnam, I'll fix it, but it's most likely it was due
to a disk or transfer error. As such, I'm going to close the bug
report. If you find a reason to think it's an Obnam bug, please either
reopen, or send a reply, and I'll reopen it.
Thank you, and sorry about the problem you're having.
