You need to install
php-imagick package via apt-get on Debian. I’m assuming you are running NextcloudPi.
sudo apt-get update && sudo apt-get -y install php-imagick --no-install-recommends
Thank you for your suggestion.
Yes, I run ncp. I have already installed php-imagick before, just without the --no-install-recommends option.
That did not help.
Afterwards, I just restarted my server and used Preview Generation app to create thumbnails. Works regardless of --no-install-recommends.
Did you install php-imagick within your Docker container? It can be accessed by ssh’ing into your machine and then accessing the container with
docker exec -it nextcloudpi /bin/bash
Do you have the Preview Generation app enabled under
/index.php/settings/admin/overview to see if any errors pop up for system dependencies.
Thx for you answer. It took me a while to respond because I had big trouble with my installation. I could (hopefully) fix it now.
ad 1) I am not using Docker, but the command line install skript for Debian. Anyhow, I have already manually installed php-imagick. This was not the problem.
ad 2) / 3) brought me to the right path: My apps page was screwed up for whatever reason and I could not see enabled/installed apps. In fact opening the apps page flooded the error log. This is what I fixed now and indeed, the preview app showed as not been installed. I had it installed in much earlier NC versions, though. Anyhow, once re-installed the preview generation runs now
