You need to check duplicati's documentation on how to deal with those errors.

Until last weekend everything was fine, the only change was the update to the latest version. To make matters worse, the latest version changed the version of the duplicati database and I can't roll back to the penultimate version. For me this is an issue.

[j0nnymoe]

Yes I get this is an issue. We package what duplicati release, this does not look like a container issue to me but an application issue. You need to see if this bug has been reported to duplicati but from my quick googling, it seems a common problem going back years.

[PacmanForever]

Okay, I understand that we only need to put container errors here.

Just to mention that I put the original image (duplicati/duplicati:latest) and everything works perfectly. Are you sure it's not an error with this image?

[thespad]

That image is over 6 months old as they stopped pushing the latest tag back in May.

See https://hub.docker.com/r/duplicati/duplicati/tags

[TobenderZephyr]

Well, that's not entirely correct
From the README on that repository:

Available tags
[...]
latest - an alias for beta

Beta has been pushed 9 days ago. This is also when i saw warnings with files being already accessed while doing the backup.

[thespad]

They can write whatever they like in the readme, it doesn't change the reality

[kenkendk]

The missing beta update in Dockerhub is my fault 🤦.
I am pushing to get the first stable release of Duplicati out, and in the process I missed getting the beta == latest tag in there, until the stable release is out.

For @PacmanForever , yes there is a need for a password for the UI in 2.0.9.104+ (so including the beta that is not in Dockerhub:latest). You can set DUPLICATI__WEBSERVICE_PASSWORD=<password> to configure it.
More password details in docs and a downgrade to 2.0.8.1 guide exists.

Since it wasn't working for me, I changed the image, now I use duplicati/duplicati:latest and everything works for me.

Thanks
