Original GitHub issue: https://github.com/netblue30/firejail/issues/3225

Info:
Fedora 30
Firejail version 0.9.60-1
youtube-dl version 2020.01.24

Command executed:
firejail --seccomp --netfilter=/etc/firejail/nolocal.net youtube-dl --help

Command expectation:
Help text provided by youtube-dl will show.

Command result:
Command ended without any feedback.

--noprofile works for reasons I am incapable of identifying.

Previously, I used firejail-0.9.58.2-1 and it worked flawlessly with youtube-dl.
Installing firejail-0.9.60-1 caused this issue for me. However, firejail-0.9.60-1 works flawlessly with my Firefox 72

What happens if you start it "normal" with firejail youtube-dl --help?
For me this is working. Fedora 31 ytdl 2020.01.24 firejail git.

The problem persists even if I use just firejail youtube-dl --help
It might be a Fedora 30-only problem at this version of firejail D:
As much as I'd like to upgrade to Fedora 31, the Fedora 31 template for the security-oriented Xen hypervisor that I am using is still in the middle of testing and I cannot upgrade yet RIP

I'm all game if ever you need more logs or stuff from me but I'm also fine with leaving this problem in the dark since I can pretty much live with --noprofile until the Fedora 31 template that I am waiting for graduates out of testing.

I've three points:

To exclude self-made issuses: has you edited any profile or .local files?
If you watch journalctl --follow while trying ytdl, is there anything related logged?
If none of the above helps, you will need to comment everything and uncomment line for line to find the problematic line.

@rusty-snake I did as you said and here are the results:

Nope, I have no reason to do that as of yet
Tried to watch journalctl --follow but nothing came up when I executed the commands that caused this problem.
After commenting out one by one, I was able to narrow it down to this line:
private-bin youtube-dl,python*,ffmpeg

IDK why this line causes the problem, it's quite weird. Maybe cause I don't have ffmpeg installed?

Looks you have the python2 version of ytdl, thats seems to be the reason. I have the python3 version.

Oh what, I don't even know if I'm getting the python2 version or the python3
All I do is go to the releases page and get the plain youtube-dl
https://github.com/ytdl-org/youtube-dl/releases/download/2020.02.16/youtube-dl

I tried getting the tar.gz archive and it contained two different youtube-dl binaries; one in the main directory of the extracted archive and one located within the bin folder.

How do I tell which is the python3 version?

You have at least four ways to install ytdl:

with dnf (as I do)
with pip
manually from https://github.com/ytdl-org/youtube-dl/releases
with wget and https://yt-dl.org/downloads/latest/youtube-dl

https://ytdl-org.github.io/youtube-dl/download.html

This file uses #!/usr/bin/env python as shebang.
/usr/bin/python is an symlink to python3 for Arch and Fedora 31, for Debian, Ubuntu, Fedora 30, .. it is still python2.

Thank you for this! I have totally forgotten about that change to python defaults so this really helped me realize things.

That should just about solve this case I believe, I am grateful for your close assistance in solving this mystery!
