OSError: [Errno 2] No such file or directory

[dobu]

Neither the automatic Backup, nor a manual backup work. They fail with the error, in the logfile.

when started in terminal, I get the following output:

errr... my title got a wrong copy/paste :-) should be:

OSError: [Errno 2] No such file or directory

[dobu (general-db)]

oh. forgot
rpm -q duplicity deja-dup

strange. fixed itself somehow. works now flawlessly... o.O

[Michael Terry (mterry)]

Oh... Odd. But good? I'll leave this open for a little bit in case it reappears. The log shows you got the error while GPG was trying to encrypt or decrypt something... I've never seen this particular error before.

I'm seeing the same error "OSError: [Errno 2] No such file or directory"

The initial backup works fine (I backup to amazon S3) but then the next backup fails:

Traceback (most recent call last):

this is the first time I'm filing a bug on launchpad, hopefully I'm doing this right, here is extra info:

Package: duplicity
Version: 0.6.08b-0ubuntu2

Package: deja-dup
Version: 14.2-0ubuntu0.1

[Michael Terry (mterry)]

Mathijs, you're doing fine. :) One thing to try is to run the following command:

rm -r ~/.cache/deja-dup

And then try backing up again. It deletes the local cache of all your backup metadata. It will be re-downloaded the next time you try to backup, so it will take a little longer.

[Michael Terry (mterry)]

Ken, I'm adding a duplicity task. I don't know what the cause of this is yet, but I suspect that os.unlink call should ignore File-not-found errors.

[Mathijs Maertens (mathijs-maertens)]

thanks, I've cleared the cash and the initial backup started over. Since this was about 50GB, for testing I reduced it to a selection with 50MB, now the problem is gone.

I had the problem twice with the 50GB selection, so I suspect one of my files or paths is causing the error. I'll try to isolate what this is. (most of the data is coming from an external USB HD)

[Mathijs Maertens (mathijs-maertens)]

the cache, not the cash ; p

[Kenneth Loafman (kenneth-loafman)]

I just pushed a fix to the repo that should fix the problem. Instead of erroring out, it just puts out a warning if the file cannot be deleted for whatever reason.
