NethServer Version: 7.7.1908
Module: Nextcloud 17.0.2
After updating nextcloud to version 17.0.2 I noticed that by logging in as admin and selecting general information, I am notified of a checksum error. I seem to have understood that this is a system app, i.e. right click where the server reports a checksum error. How can I solve the problem ?
I attach error
Please try this command and report here the output:
rpm -V nextcloud
By the way, you can safely ignore the check on a README file

Thank you, everything seems fine.
Even if really ugly for a RPM 
You’re README file shouldn’t be there, probably has been added by an application. I have the same on my installation, but I couldn’t find which README was causing it (there are plenty inside the nextcloud dir).
You can ignore the warning, if you need further info please see the official doc: Code signing — Nextcloud latest Administration Manual latest documentation
thank you very much
