The backup is finished, but after the check the program reports:

This looks like a hard-to-diagnose problem in duplicity that we've seen before. See:
https://bugs.launchpad.net/duplicity/+bug/498933

Can you try the snap version that bundles the latest version of duplicity with it, to see if that helps?

sudo apt remove deja-dup
snap install deja-dup --classic

Hi,
I could not post this comment on launchpad, got a very big error message in html.

After the snap installation of DejaDup, the program got stuck on a large (30 Gb) file; even after several tries and many hours. There was no error message and no information in the log file.
I have now created a completely new backup and it went well.

Thank you for your effort.

Regards
Wolfgang
