I have an issue since today but I’m not sure if it’s a problem with the new 32.0.0.5 update.

At my external USB drive there are a lot of HEIC files. The USB drive is mounted in /media/usb/. Via crontab I let generate previews from all of my pictures.

But since today I get the following error messages and the photo viewer doesn’t show the pictures. That’s an example message

ImagickException
unable to open image `/media/usb/Bilder USA 2025/Bilder Mario/202510__/IMG_5792.HEIC’: No such file or directory @ error/blob.c/OpenBlob/2924

Have somebody the same issue or an idea what I can do ?

Thanks for your support!

It seems, your Nextcloud files are in /admin/files/Lokal/Bilder USA 2025/Bilder Mario. So why should Nextcloud use /media/usb/Bilder USA 2025/Bilder Mario instead? Can you explain the workflow a bit more detailed? I would expect, that you have to copy the files from the USB stick to Nextcloud first before any preview or opening the image is possible at all.

I will try to describe my workflow - sorry, I hope you can understand my english.

My USB Hard drive is mounted in /media/usb

mario@nextcloud:/media/usb$ sudo mount
…
/dev/sda1 on /media/usb type fuseblk (rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)

Therefore all of my pictures are in the folder

mario@nextcloud:/media/usb$ ls -la
…
drwxrwxrwx 1 root root 0 Dec 11 08:17 ‘Bilder USA 2025’

In the NC GUI this folder is as Local External Storage embedded (Pic01).

Pic01
Pic011498×378 40.6 KB

Then I use the photo app and I set this local storage as media folder in his settings (Pic02).

Pic02
Pic02989×598 26.1 KB

As last I let generate new previews with the following command.

mario@nextcloud:/media/usb$ sudo -u www-data php /var/www/nextcloud/occ preview:generate-all -vvv

I have never copied files from “/media/usb/…” to “/admin/files/Lokal/…”. But maybe that is a fundamental mistake of me about the External Storage feature.

To me this looks like a bug in Nextcloud itself. You should report this at Github (https://github.com/nextcloud/server/issues).
