Original GitHub issue: https://github.com/netblue30/firejail/issues/2348

Recently, (I do not know precisely which commit), dolphin SMB integration has stopped working.

The error in dolphin is "the protocol has died unexpectedly". This is a symptom of the error in kio or samba which is "Could not determine network interfaces, you must use a interfaces config line". Adding an explicit interface in samba.conf does not fix the issue.

I've traced it back to the "protocol = unix" line in the dolphin profile. "protocol = unix,netlink" gives a different error about being unable to identify the workgroup.

"ignore protocol" fixes the issue.

Thanks.

Thanks for reporting the issue.

Can you try protocol unix,inet,inet6,netlink? If this works, could you please confirm that all of them are required?

Needs at least "protocol unix,inet,netlink" to work.

Interestingly, I get the "protocol died unexpectedly" error if I try to open certain files through dolphin with, for example, GwenView. Commenting out "protocol = unix" in gwenview.profile fixes it. I expect that any program with a restrictive protocol filter will have similar problems over SMB, so this might not be a dolphin-exclusive issue.

You are right, all kio dependent apps are affected.

If you add rmenv KDE_FORK_SLAVES to /etc/firejail/globals.local, it should bring back the old behaviour. But I think the recommended way is rather to adjust the protocol lines to your needs.

Maybe we can relax the default Dolphin profile in this regard.
