How to install the Previewgenerator?

In order to speed up preview loading and the general feel of Nextcloud while opening folders with many pictures, you should set up the previewgenerator, which will pre-generate previews to make preview-loading faster.

  1. Run over CLI:
    sudo bash /var/scripts/menu.sh
  2. Choose Additional Apps -> PreviewGenerator
  3. Choose to install/reinstall the Preview Generator
  4. Choose to not install imagick
  5. Deselect any format you don't want to have previews for (Recommended is to deselect MarkDown & TXT)
  6. Wait until everything is set up
  7. Choose to not use a specific Nextcloud user for preview generation
  8. Wait until everything is scanned. This can take a long time, please be patient! (If it just takes too long and doesn't finish, you can cancel by pressing ctrl + c. You could then run this script after the initial setup is done.)
