The Problem

I'm using Deja Dup to back up my recently restored and upgraded Ubuntu 11.10 machine. However, only one backup has ever succeeded; in every subsequent backup, I was continually asked for my encryption password. It turns out that this is a previously fixed bug and, as such, I reported it as having potentially regressed. While I wait for a fix, however, this leaves me with a broken backup program that I can't use. Because my system is somewhat unstable, I need this backup to work now; it's led me to look for workarounds.

The Potential Workaround

I've inferred from this post that I can clear the settings for duplicity and Deja Dup by eliminating ~/.cache/duplicity and/or ~/.cache/deja-dup and my old backups. This will allow me to change the settings that are (supposedly) causing the bug and let me do backups normally.

Why I Need Your Help

To make the workaround work, I need to delete my old backups. My old backups are stored on the Ubuntu One cloud. However, I can't figure how to delete files as there isn't a local copy. I know that there is an API call to do this, but there must be a more elegant way to delete these files.

Long Story Short...

How can I delete files on Ubuntu One that have no local copy that can be manipulated?

For alternate backup solutions see . Why is your system unstable and can we help you fix the underlying problem ? – bodhi.zazen Dec 23 '11 at 23:48
It's a hardware problem and has nothing to do with Ubuntu. Thank you for your concern, however. – Dylan Knowles Dec 24 '11 at 1:11

You know, looking for a tutorial would make a lot of sense, haha. I don't know why I didn't think of it in the first place. Thank you! – Dylan Knowles Dec 24 '11 at 1:09
