Following an erroneous update, (due to a full disk), I have the following message when I want to restart the update via the web page:

Checking the expected files
The following additional files were found :

I have deleted the files in the backups and downloads folder, but I don’t know how to reset the “.step-previous-update”.

Where is this setting?

thank you in advance

I found my problem, I had to delete the folders (backups, donwload and step-previous-update)

The step-previous-update file is a hidden folder, with the ls -a command it is visible.

I succeeded in upgrading to Nextcloud 22.1.1
