Deja Dup keeps asking for password

[Keith Drummond]

Ubuntu 11.10

The last 2 days whenever an automatic backup runs it asks me for my password, which I input. The GUI then says 'preparing backup', before asking for the password again. The password I am inputting is correct, so I am not sure why the backup is not running

Can you upload the file /tmp/deja-dup.log after running the following?

DEJA_DUP_DEBUG=1 deja-dup --backup | tail -n 1000 > /tmp/deja-dup.log

As a workaround I have removed the old backup folder and now have Deja Dup pointing to a different folder. The first backup was a full backup and everything went fine. With the previous settings I had changed the option of 'saving 6 months' to just saving the last 3 months. It was after that the error occurred and I could no longer make a backup.

The terminal command seems to have run a backup with no problems to the new directory. I had to remove the old one to make space in my backup location, and 6 months worth of backups. Sorry that I can not provide any further details now.

This happens to me also, started to occur after installing/setting up gpg for email.
Did the log thing as suggested, parts that are probably relevant (slightly adjusted/anonimized):

Looks like a duplicate of https://bugs.launchpad.net/deja-dup/+bug/840393
Which is a duplicate of:
https://bugs.launchpad.net/deja-dup/+bug/681002

[Launchpad Janitor (janitor)]

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

[Naël (nathanael-naeri)]

Not a duplicate of #840393/#681002 because the GPG error is different (not "Bad CA certificate").

However it looks like it's the same as the one reported by Mathias Binke in #989750.

[Naël (nathanael-naeri)]

Also, same signs of full backups succeeding, so probably same bug as #989750 indeed
