Digikam does not see ZFS folders

Software digiKam
1

Hi guys,
I’m running Ubuntu 20.04, digiKam 7.3.0
After a recent harddrive failure, I migrated all my photos to a zfs file system.

The folders and all contents are visible and writable *except by digikam.
Digikam does not see the folders at all.

The folder does not appear in the browse list.
When I enter the location manually, I get
“The folder to use as the root album path does not exist:
/tank/data/Pictures
Would you like digiKam to create it for you?”

I don’t see anything in the forums or on-line about this problem or possible solutions.
I don’t know where to start.
Any help appreciated.

Thanks,
Dave

How did you install digikam? Deb package? Snap? Flatpak? AppImage?

Are the file permissions correct?

Thanks Mica.
It looks like I have 2 versions installed. I don’t know how that happened.

I have 6.4.0 installed through apt (sudo apt-get install digikam).
That version sees the zfs shares

I also have 7.3.0 installed as a snap package. I don’t remember installing that.
I’d prefer to use the newer version, but it’s this snap package that does not see the zfs shares.

The snap package is sandboxes (and Ubuntu is starting not to distinguish between native and snap packages in their software store). You could try the flatpak and modify the sandbox permissions if necessary.

Thanks.
I’m at work now, but I’ll try to reinstall the 7.3 version when I get home tonight.

Cheers,
Dave

I tried refreshing the snap, but that didn’t change anything so I removed and reinstalled.
Still no joy.
Digikam 7.3.0 installed by snap does not see my zfs drives.

I’m not sure if this is a digikam problem, or an issue with snap itself.
This post seems similar. filesystem - Snap programs show only files inside /home - Ask Ubuntu

oh dear.
snap is not broken, it’s deliberately not allowing access.

I think I’ll just stick with 6.4.0 for now.
Thanks @Mica for your help.

The snap won’t work as you can’t modify the sandbox permissions.

The flatpak, which is a different package format, allows you to modify the sandbox permissions and will give you an up to date version.

Cheers @paperdigits , the flatpak installation works great, so I’m on v 7.3.0 now!
Hooray!

I found the flatseal tool was very helpful in setting permissions.

Thanks again.
Dave
