after reading related threads I realized, how brittle duplicity is for backups. Anyway, for some strange reasons deja-dup stopped working:
- first I got an error similar to this (probably made some small change to keyring / seahorse / gpg before, but I cannot remember exactly
- I then apt-get removed deja-dup and duplicity and
- snap installed latest version of both
Now I'm stuck with a new "known" error:
Backup keeps asking for Encryption Password while restoring
which nobody (including me) was really able to recover from.
Here is the command line output when I start the 'snap'-ed deja-dup from command line using
export DEJA_DUP_DEBUG=1
deja-dup --backup
here is the error message:

my current snap versions are:
deja-dup 42.7 duplicity 0.8.19
Problem was that I had used different passwords for backups and duplicity did not warn me when doing so. So in order to fix it I had to delete files with the different password in use. It's explained here
