Déjà Dup

Deja Dup failed Backup

Asked by Roger Quenneville

Hello, following a recent update of the OS of my Ubuntu 20.04.03 LTS, made by the update manager, I received the following error message, when trying to backup '' Data invalid - unverified SHA1 fingerprint for file: ......''
This has happened to me several times, always when updating the OS. I am somewhat annoyed that I have to start all over again with each OS update. Is there a way to resolve this issues?
(Hoping that the translation made by google translate is understandable)

With research following my questions and the answer received on Ubuntu / fr, I decided to install another program. What I find most disappointing is that this program is still included with the Ubuntu install, knowing full well that it doesn't work as expected. It would be better to offer nothing rather than a lame duck. Not being accustomed to forums, nor to the structure of Ubuntu, I don't know where I could send my request.

Hey - sorry that Deja Dup was giving you troubles. It *should* work as expected though!

Would love to help debug this, but I understand if you have moved on. Sounds like one of your volume files got corrupted. We can work around that issue by removing the volume file.

This looks like maybe another instance of https://bugs.launchpad.net/deja-dup/+bug/487720 ?

Which is a duplicity bug, not a deja-dup one, but still - they are related.
