Hi,
after installing Nextcloud via Dietpi-software there arre some Issues to fix. One of these is a missige module called “libmagickcore”.
In the FAQs there is fix, but this fix points to a version which isnt available anymore.
We propose to ignore them: imagick is not needed at all and a subject of discussion about security issues, bcmath and gmp are required only if you want to use the WebAuthn passwordless authentication with Nextcloud.
