Original GitHub issue: https://github.com/netblue30/firejail/issues/6910

I recently updated from antix22 to antix23.2 operating system. On antix22, I was using firejail 0.9.64.4-2, and playonlinux worked. antix23 came with firejail 0.9.72, but I upgraded to 0.9.74, because Firefox and Librewolf (and others) didn't load right in firejail.

With Playonlinux on firejail 0.9.74, I have gotten passed several error messages, by whitelisting several directories in playonlinux.local. Now, the process stops with "permission denied". Perhaps that means permission needs to be changed on some file or directory. But how do I locate the point of denial?

"firejail --noprofile playonlinux" loads properly.

Thank you.

Here is additional information. Let me know what else might be helpful.
The O.S. is Antix23.2, 64 bit (Debian bookworm, without systemD). Computer is Dell Latitude E5430.
PlayOnLinux is version 4.3.4.
More than one error, including failed to create DBus proxy for org.ally.Bus were bypassed by whitelisting several directories in playonlinux.local (I see that several of these entries are already covered by relevant firejail profiles, but I haven't taken time to delete unneeded ones from the list.) Here is my playonlinux.local

whitelist /usr/bin/nc
whitelist /usr/lib/firejail/seccomp.debug32
whitelist ${HOME}/.PlayOnLinux
whitelist ${HOME}/~PlayOnLinux's virtual drives

whitelist /usr/bin/playonlinux
whitelist /usr/bin/playonlinux-pkg
whitelist /usr/share/wine
whitelist /usr/share/applications

whitelist /usr/share/playonlinux/playonlinux
whitelist /usr/bin/python3

With the above, running "firejail playonlinux" in terminal produces the following:

@davew-fj commented on GitHub (Sep 25, 2025): Here is additional information. Let me know what else might be helpful. The O.S. is Antix23.2, 64 bit (Debian bookworm, without systemD). Computer is Dell Latitude E5430. PlayOnLinux is version 4.3.4. More than one error, including `failed to create DBus proxy for org.ally.Bus` were bypassed by whitelisting several directories in playonlinux.local (I see that several of these entries are already covered by relevant firejail profiles, but I haven't taken time to delete unneeded ones from the list.) Here is my playonlinux.local ``` whitelist /usr/bin/nc whitelist /usr/lib/firejail/seccomp.debug32 whitelist ${HOME}/.PlayOnLinux whitelist ${HOME}/~PlayOnLinux's virtual drives whitelist /usr/bin/playonlinux whitelist /usr/bin/playonlinux-pkg whitelist /usr/share/wine whitelist /usr/share/applications whitelist /usr/share/playonlinux/playonlinux whitelist /usr/bin/python3 ``` With the above, running "firejail playonlinux" in terminal produces the following: ``` $ firejail playonlinux Reading profile /etc/firejail/playonlinux.profile Reading profile /home/my3epc/.config/firejail/playonlinux.local Reading profile /etc/firejail/allow-perl.inc Reading profile /etc/firejail/allow-python2.inc Reading profile /etc/firejail/allow-python3.inc Reading profile /etc/firejail/wine.profile Reading profile /etc/firejail/disable-common.inc Reading profile /etc/firejail/disable-devel.inc Reading profile /etc/firejail/disable-interpreters.inc Reading profile /etc/firejail/disable-programs.inc Reading profile /etc/firejail/whitelist-var-common.inc firejail version 0.9.74 Parent pid 3326, child pid 3327 Base filesystem installed in 44.90 ms Child process initialized in 110.00 ms Cannot start application: Permission denied Parent is shutting down, bye... ``` Running `firejail --debug playonlinux` produces the following: <details> <summary>debug log</summary> <p> ``` $ firejail --debug playonlinux Looking for kernel processes Found kthreadd process, we are not running in a sandbox pid=3451: locking /run/firejail/firejail-run.lock ... pid=3451: locked /run/firejail/firejail-run.lock pid=3451: unlocking /run/firejail/firejail-run.lock ... pid=3451: unlocked /run/firejail/firejail-run.lock Building quoted command line: 'playonlinux' Command name #playonlinux# Found playonlinux.profile profile in /etc/firejail directory Reading profile /etc/firejail/playonlinux.profile Found playonlinux.local profile in /home/my3epc/.config/firejail directory Reading profile /home/my3epc/.config/firejail/playonlinux.local Found allow-perl.inc profile in /etc/firejail directory Reading profile /etc/firejail/allow-perl.inc Cannot access .local file allow-perl.local: No such file or directory, skipping...
