Hello everyone,

I am currently experiencing errors during a maintenance run:

```auto

```

Backup still works. I performed maintenance on another machine while my backup machine was turned off.  
How do I fix/remove these errors?

Any help is appreciated!

Same situation here, a lot of my repos start showing these errors during maintenance after upgrading to 0.15.

The fix invalid-files command scaringly also finds and removes invalid entries, but maintenance doesn’t succeed regardless.

Any suggestions would be highly appreciated, since I fear my backups are not reliable anymore and simply reuploading is not an option due to the amount of data and data consumption during upload.
