ERROR: No such file: u'/home/martin/ubuntu/apport/ubuntu/.bzr/repository/obsolete_packs

[Martin Pitt]

Occasionally, I get errors like this on commit:

bzr: ERROR: No such file: u'/home/martin/ubuntu/apport/ubuntu/.bzr/repository/obsolete_packs': [Errno 2] No such file or directory: '/home/martin/ubuntu/apport/ubuntu/.bzr/repository/obsolete_packs'

Once I commit again, it works fine again. That's what makes it pretty hard to reproduce, since when I see it, it is too late to snapshot the previous version of the branch. Do you have an idea what's going on, or what I can do to provide better debug information?

You deleted the obsolete_packs directory at some point in the past.
recreate it, and don't delete it again :)

Hm, I am not really aware of ever having touched this directory. I don't poke below the .bzr/ directory usually. Also, I saw this happen on both my laptop and my desktop.

So if this really is an user error, feel free to close this report; I just don't remember deleting it. OTOH this checkout is two years old, > 1000 commits, and saw many different bzr version and conversions, so it might have accumulated some cruft.

Do you have a traceback for this by any chance?

Ah, .bzr.log still has it:
