SUMMARY
Digikam freezed during file transfer. Result: of 0 byte files at destingation while being DELETED FROM SOURCE DIRECTORY BEFORE TRANSFER IS COMPLETE, HOW!!?? I had to force restart because processes couldn't be terminated - filesystem check didn't find anything on reboot. I should have backups, but this just can't happen!!

Comment 1 Maik Qualmann 2022-07-04 18:48:50 UTC

We can only help to a limited extent, the Ubuntu Snap packages have a sandbox. This blocks access to external directories for digiKam. The File Export Tool does not delete source files. If you move via drag&drop or copy/paste, deleting the source file is fixed in current digiKam versions if it fails. Use our AppImage and delete the useless snap package.

This should be fixed from 7.5.0 within Ubunut (whatever the procedure is) as it is in Latest LTS of Ubuntu and likely has many users.

Comment 3 Maik Qualmann 2022-07-04 19:55:27 UTC

The digiKam included in Ubuntu is unusable, this is not the first bug report we have received for the Snap package. All sorts of problems arise due to the sandbox. The Local File Copy Tool never deletes the source file, it's impossible. Only the target file will be deleted if you have overwrite enabled. Check your file system, hard drive, etc.
