Description

I'm using firejail on Arch Linux with XFCE desktop. When starting simple-scan via firejail, I can not save the scanned documents, the "save file" dialog does not even open. Running simple-scan directly works fine.

Steps to Reproduce

Steps to reproduce the behavior

  1. Run in bash LC_ALL=C firejail /path/to/program (LC_ALL=C to get a consistent output in English that can be understood by everybody)
  2. Start scan
  3. Click on the "Export" button (left of the hamburger menu)

Expected behavior

The "Save file" dialog should open.

Actual behavior

When I click on the "Export" button, nothing happens.

Behavior without a profile

What changed calling LC_ALL=C firejail --noprofile /path/to/program in a terminal?
Works normally.

Additional context

Any other detail that may help to understand/debug the problem
As I'm using simple-scan rarely, I can not tell when the problem was introduced. What I know is: Maybe it never would have worked with firejail, but was not included in /etc/firejail/firecfg.config until recently.

Environment

  • Name/version/arch of the Linux kernel (uname -srm):
    Linux TuxServer 6.12.23-1-lts #1 SMP PREEMPT_DYNAMIC Thu, 10 Apr 2025 13:28:36 +0000 x86_64 GNU/Linux
  • Name/version of the Linux distribution (e.g. "Ubuntu 20.04" or "Arch Linux"):
    Arch Linux
  • Name/version of the relevant program(s)/package(s):
    simple-scan 48.1-1
  • Version of Firejail (firejail --version):
    firejail version 0.9.74
  • If you use a development version of firejail, also the commit from which it
    was compiled (git rev-parse HEAD):
    N/A

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
  • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

I can reproduce this issue as well, Arch Linux with GNOME.

As I'm using simple-scan rarely, I can not tell when the problem was
introduced. What I know is: Maybe it never would have worked with firejail,
but was not included in /etc/firejail/firecfg.config until recently.

It looks like it was included in firecfg.config on commit bc257b6a4 ("added
akregator, kcalc and ktorrent profiles", 2017-04-24), so not exactly recently.

firejail version 0.9.74

What happens in 0.9.76?

(simple-scan:6): Gtk-WARNING **: 17:41:09.504: Creating a portal monitor failed: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Portal operation not allowed: Unable to open /proc/705481/root
MIB search path: /home/markus/.snmp/mibs:/usr/share/snmp/mibs
Cannot find module (SNMPv2-MIB): At line 0 in (none)

What happens with the following in simple-scan.local?

whitelist /usr/share/snmp

For debugging, try commenting lines in the profile until it works to find out
which lines are causing problems and then post them in here.
