if the problem not solved..can i reinstall ubuntu 11.10 to make my system as fresh as before??????

[Michael Terry (mterry)]

You mention "can't restore to original location." Can you restore to a specified folder instead of choosing the "Original location" option?

I'm not sure why this would happen. "Argument list too long" is an odd error to get when closing a file.

I have a drastic thing you could try:
1) sudo gedit /usr/lib/python2.7/dist-packages/duplicity/robust.py
2) Find the line that looks like:
              'EIO', 'ETXTBSY', 'ESRCH', 'EINVAL'])):
3) Edit it to look like:
              'EIO', 'ETXTBSY', 'ESRCH', 'EINVAL', 'E2BIG'])):
4) Try again and let me know how it worked.

[Michael Terry (mterry)]

Ken, do you have any ideas what "Argument list too long" would mean in this context?

[shevos (shevos37)]

i don't understand that problem.or how to be solved..i tried (no.1) which you gave me( suo gedit /usr/lib.......etc.. and here what i got:# -*- Mode:Python; indent-tabs-mode:nil; tab-width:4 -*-

 i need this problem to be sloved pls.thanks in advance. wish you all the best

[Michael Terry (mterry)]

OK, try this:

1) Download this attachment (robust.py)
2) Open a Terminal (Ctrl+Alt+T)
3) sudo cp Downloads/robust.py /usr/share/pyshared/duplicity/robust.py
4) Try backing up again

Let me know how that works.

Status changed to 'Confirmed' because the bug affects multiple users.

[Kenneth Loafman (kenneth-loafman)]

Could you run this one again with -v9 and attach the log to this bug report.

If the log is too long, attach just the first 200 lines and the last 200 lines. The middle part is normally not useful.
