Original GitHub issue: https://github.com/netblue30/firejail/issues/2001

I've noticed that Ark does not open zip files on Fedora 28 KDE. Using firejail-git.

Commenting the private-bin line fixes the problem. So it seems that something is missing in that line. I haven't been able so far to find it.

Does it work under the release version (0.9.54)? Because just looking at the profiles, there doesn't seem to be anything significantly different in terms of the profile between the current dev version and the current release version.

Just tested 0.9.54 on Siduction. zip files aren't opened, either.

Hmm, okay. You can try commenting out private-bin and running strace, which might help you catch which binaries are not being included.

I tried it with

strace -e trace=file /usr/bin/ark

but didn't find an executable in the output that wasn't already included (except ldd but that didn't make a difference).
In journalctl I'm getting the error:

ark[29214]: Empty filename passed to function

Huh, that's interesting. I wonder why commenting private-bin fixes that...normally, seeing that would make me think some files aren't accessible in the sandbox, so it would be more of a private or whitelist issue...

I think I fixed it
can you try with the following?

private-bin 7z,ark,bash,dash,lrzip,lsar,lz4,lzop,p7zip,rar,sh,tclsh,unar,unrar,unzip,zip,zipinfo

Thanks - this works! Great. bash,dash is not needed here, though.

A general question for future cases: is there a systematic way to find those needed binaries other than the above mentioned strace -e trace=file ... ?

Awesome, I'll commit that. And I think bash is actually needed from what I saw.

And I just used strace, it was just a bit buried to find that it was needed.

Here were the actual commands I used

strace -fv -o test.log ark test.zip
grep "ENOENT" -v test.log | grep "/bin" > bins.txt

then I deduplicated bins.txt and sifted through it.
And sure enough tclsh and bash were being passed to execve.

I wonder if perf is even more helpful here. I think I'll have to do some digging.
