Description Alexander Wilms 2022-08-18 21:44:00 UTC

SUMMARY

STEPS TO REPRODUCE
1. flatpak remote-add --if-not-exists kdeapps --from https://distribute.kde.org/kdeapps.flatpakrepo
2. flatpak install org.kde.skanlite//master
3. flatpak run org.kde.skanlite//master

OBSERVED RESULT
Ternminal output:
_IceTransSocketUNIXConnect: Cannot connect to non-local host localhost.localdomain
_IceTransSocketUNIXConnect: Cannot connect to non-local host localhost.localdomain
Qt: Session management error: Could not open network socket

Skanlite window:
Sorry. No devices found.

The SANE (Scanner Access Now Easy) system could not find any device.
Check that the scanner is plugged in and turned on
or check your systems scanner setup.
For details about SANE see the SANE homepage.

EXPECTED RESULT
Scanner gets detected, like in Skanlite Version 22.04.3 installed from the openSUSE Tumbleweed RPM repository

SOFTWARE/OS VERSIONS
Linux: openSUSE Tumbleweed
KDE Plasma Version: 5.25.4
KDE Frameworks Version: 5.97.0
Qt Version: 5.15.5

ADDITIONAL INFORMATION
scanimage -L
device `brother4:net1;dev0' is a Brother MFC-J6510DW MFC-J6510DW

org.gnome.OCRFeeder and org.kde.skanlite//beta from Flathub don't detect the network scanner either.

Thanks for the report.

The reason is most probably that you do not have the device specific sane driver/backend installed. check if there are brother-specific packages for sane or then go to brothers support pages and download their driver there.

Then it might be easier to get to work with native packages as the sand-boxed flatpacks might not see system installed extra backends

I hope this helps to get your issue resolved.

Regards,
 Kåre

Yes, I had already installed the scanner driver using Brother's driver install tool and I can scan without problems using Skanpage, Skanlite or Simple Scan installed from openSUSE's RPM repository.
