Bug ID: 495664
Summary: Skanlite fails with message "opening the selected
scanner failed"
Classification: Applications
Product: Skanlite
Version: 22.12.3
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: kare.s...@iki.fi
Reporter: djar...@kde.org
Target Milestone: ---
Whenever I run skanlite, it reports that it has found my scanner (a Samsung
Xpress M2885FW printer), but then immediately replaces that message with
"opening the selected scanner failed". Clicking Ok then exits skanlite. XSane
works successfully, however.
This failure only occurs on my laptop, whereas on my desktop it works ok,
despite both computers having Debian Stable installed (both of which have all
the latest updates installed). I normally have a firewall running, but even
when I disabled the firewall, the error still occurred.
I ran skanlite with SANE debugging enabled, using the command
SANE_DEBUG_AIRSCAN=5 skanlite
The debug output is shown under ADDITIONAL INFORMATION below.
