Question #288602 on Duplicity changed:

Description changed to:
Hello,

I am trying to make a backup using Duplicity. I generate the key, I can
start the first backup, but this backup fails after few successfully
backup parts for lost connection (which doesn't make sense - the
connection is reliable and SSH has keepTimeAlive set to 100s).

Anyway, when I want to restart the backup again, it never runs - it
fails on gpg verification, even though it's nonsense (I am using still
the same key, same command)...

I have tried it twice with new set of keys, but still the same result.
Weird think is that when I generate the key and then run the script, it
doesn't ask for a passphrase. But on a second run it does.

Here is my backup script:
[code]
#!/bin/sh

$(which duplicity) -v5 --encrypt-key 6B5xxxx2 --exclude-filelist=bckp_excl.txt / scp://backup_server//scratch/backups
[/code]

and here is a log with failure and consequent run
[code]
