I recently set up Nextcloud, and so far I’m really enjoying it. With the exception of Gmail and Backblaze, I’m no longer using any online services that aren’t self-hosted on my own hardware; Nextcloud has allowed me to get rid of the last few Google services I was using.
One issue I’m having is that images I have uploaded to Nextcloud do not have thumbnails when the image size is large. My phone takes photos at 200MP, so this constitutes a significant number of my photos.
I’ve been researching the problem, and I think I need to set the following:
I’m running Nextcloud on a Proxmox hypervisor with 32 cores and 128GB of memory, so I’m not concerned about using system resources; I can always allocate more.
The issue I’m having is that I installed Nextcloud as a snap in Ubuntu Server. The last time I tried to use nextcloud.occ to change a configuration option, it set a string as an array, and triggered a bunch of php errors.
As far as I can tell, I need to do something like this:
sudo nextcloud.occ config:[something, maybe system]:set preview_max_x [some data goes here]
How do I format this so that nextcloud.occ inserts the variable into my php config properly? Any examples of a nextcloud.occ command would be very much appreciated.
So it should be something like sudo -u nextcloud /usr/bin/php /var/www/nextcloud.example.org/occ config:system:set preview_max_x --value="1500" (worked for me, standard PHP install, you will have to adapt it for your snap-based install). Or you can insert preview_max_x directly at the root of your config.php as shown in nextcloud’s sample config file above.

Thanks! Adapting the command you gave to work with snap will be fairly easy. Regarding a backup of config.php, I’ve tried to do that, but with a snap install, I get a permission denied error when I try to enter the config directory, and you can’t “sudo cd.” I’ll try logging in as root or changing permissions.
