libseccomp.so.2 exists though:

libseccomp.so.2 exists though:

But not in the sandbox due to private-lib.

Can you try with firejail '--private-lib=libseccomp.so.*' file whatever.

IMHO we should drop private-etc and private-lib from the file profile. It causes a lot of lookups to fail like this one, which doesn't help makepkg on Arch for instance.
