Script "nc-apps" - a helpful and more verbose complement to `occ app:list`

Integrated the script into my nextcloud container (via Dockerfile +) and it throws this:

root@NCapp:/var/www/html# nc-apps 

     First run, checking integrity:
     ===========================================================================
gpg:                using RSA key 3EE43A84D2BA635A94E1033B0B145139A170715C
     ---------------------------------------------------------------------------
     - Integrity check failed. The script may have been modified or tampered with!
     ---------------------------------------------------------------------------
     You should run:

     sudo wget -O /usr/local/bin/nc-apps https://global-social.net/apps/raw/s/nc-apps

     to fix this.
     ===========================================================================

Of course I didn’t modify the script.
Any idea how to circumvent this?
