Hi Willem,

For me this sounds like a permission problem when using snap.

According to https://askubuntu.com/questions/1034030/how-to-get-access-to-usb-storage-from-an-application-installed-as-snap, you can use "snap connect some-snap-name:removable-media" to allow an application installed by snap to use external media. Assuming that the subsurface snap is simply calles "subsurface", the command should be "snap connect subsurface:removable-media".

Best regards
Christof

My photographic images are on an external hard drive, labeled as 'TOSHIBA EXT. I cannot access the images from within subsurface.This coincidental with moving to a fresh newly-intalled Ubuntu on a new clean machine.

I use Ubuntu 23.10

PROBLEM 1:
------------------
Permissions for the external drive as follows:
willemf@fergusn:/media$ ls -l willemf
total 4
drwxrwxrwx 1 willemf willemf 4096 Nov 19 16:45 'TOSHIBA EXT'

Obviously I work in the media directory located in the root directory and the first part of the path is /media/willemf/'TOSHIBA EXT'

The system location of one such image is:
willemf@fergusn:/media/willemf/TOSHIBA EXT/Fotos/Sodwana.2023 Mei/darktable_exported
The relevant image in the above directory is:
$ ls White*
'Whitespotted butterflyfish Chaetodon kleinii.jpg'

The path and existence of the image is explicit.

The divelog reference of the above image is:
<picture filename='/media/willemf/TOSHIBA EXT/Fotos/Sodwana.2023 Mei/darktable_exported/Whitespotted butterflyfish Chaetodon kleinii.jpg' offset='+30:35 min'/>

The reference in the divelog appears correct. Granted, the spaces in the reference cause complications but Linux can easily deal with that by using the ' ' notation.

Subsurface does not recognise any of these references in the dive log and consequently shows an "Image not found" icon in the media panel of Subsurface. I have no idea how to address this issue.

The above issue possibly relates to:

PROBLEM 2:
------------------

Cannot set image directory in Subsurface GUI

Screenshot from 2023-11-22 10-24-49.png

When I try and set the directory with images, it does not se anything within the media directory. Consequently it is impossible to import images into Subsurface. The above media directory is the one in the root.

Could this be an installation issue on my side? I installed the snap from the Subsurface website and did not build it myself.

One last gripe. My installation of Subsurface does not show a launch screen and directly goes to the full GUI with all the dive information. Thus I do not know which version of Subsurface I work with. But the snapĀ  was installed 4 days ago. I cannot find the Subsurface log file.

Kind regards, Willem
