When doing a restore "Checking for Backups" and nothing happens?

Henrik, a bug was fine too, no worries.

It might take a while, but it should eventually ask you to choose from a list of backup dates. How long have you waited? Where are the backup files kept (e.g. ssh server, amazon s3, external hard drive)?

If this is time sensitive, try the instructions here: https://live.gnome.org/DejaDup/Help/Restore/WorstCase

That will at least allow you to get data back, even though it won't be as convenient as the graphical interface.

I have the backups on a USB stick, and I had it waiting for more than an hour
Also when I try to make a backup, then it only waits with the texts:
"Backing up..."
"Preparing..."
yellow bar left right
Details is empty

So neither restore nor backup works

the instructions at https://live.gnome.org/DejaDup/Help/Restore/WorstCase
does not work because it says that my password is wrong although I remember it correctly

Synchronizing remote metadata to local cache...
Copying duplicity-inc.20110516T112539Z.to.20110517T062803Z.manifest to local cache.
GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: CAST5 encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: bad key
===== End GnuPG log =====

Now when I tried to make a backup it says
"Backup location not available"
"Waiting for 'USB DISK 2.0: PENDRIVE' to become connected..."
But, my usb stick is still in place, I can browse it with nautilus, no problem there

There are so many things going wrong here, I don't know where to start.

Try unplugging/inserting the USB stick?

When you manually ran duplicity, it prompted for your encryption password? And you're very confident you entered it right both times (originally and when restoring) I assume.

You might try deleting ~/.cache/deja-dup to see if there is an odd metadata bug preventing a backup.

You might also try backing up to a different folder on the stick? I'm curious if that backup set is just in some crazy state.
