Description

cannot launch rssguard

Steps to Reproduce

firejail rssguard

Expected behavior

see the gui

Actual behavior

nothing happend

Behavior without a profile

successfully run the app

Additional context

already setup apparmor

Environment

  • Name/version/arch of the Linux kernel (uname -srm): Linux 6.12.29-1-lts x86_64
  • 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) (e.g. "firefox 134.0-1,
    mesa 1:24.3.3-2"): rssguard 4.8.4-1
  • Version of Firejail (firejail --version):
    firejail version 0.9.74
    Compile time support:
    - always force nonewprivs support is disabled
    - AppArmor support is enabled
    - AppImage support is enabled
    - chroot support is enabled
    - D-BUS proxy support is enabled
    - file transfer support is enabled
    - IDS support is disabled
    - Landlock support is enabled
    - networking support is enabled
    - output logging is enabled
    - overlayfs support is disabled
    - private-home support is enabled
    - private-lib support is disabled
    - private-cache and tmpfs as user enabled
    - sandbox check is enabled
    - SELinux support is disabled
    - user namespace support is enabled
    - X11 sandboxing support is enabled
  • If you use a development version of firejail, also the commit from which it
    was compiled (git rev-parse HEAD):

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)

firejail rssguard

Running firejail in firejail can cause issues (see #2877), so it's recommended
to run either rssguard or firejail /usr/bin/rssguard.

the application works after these changes.

Should be fixed by:
