I backed up my system a while ago and now when i reinstall Ubuntu 19.10, i tried to restore it from the backup but after a lot of trials i could not get duplicity to work, it always return the error

duplicity.dup_collections.CollectionsError: No backup chains found

My command is

duplicity restore "file:///media/user/2bhd/backup/" /back

I checked the path several times by adding, removing slashes but it is still the same so that could not be the reason why.

It turns out that there is no duplicity signature file


in the backup directory so that maybe is the reason duplicity does not work so i wanted to ask if there is any possibility of restoring my files without the signature file.

  • @user535733 i tried that but the main problem, i think, is the missing signature file

  • no collections, no backup ;). head over to the duplicity mailing list and provide a list of files on your backend. ..ede/duply.net Commented May 13, 2020 at 10:41

duplicity collection-status "file:///media/user/2bhd/backup/"

does not return any valid backup chains, then your backup is corrupted unfortunately.
