You are trying to install a package from upstream (firejail_0.9.56-LTS_1_amd64.deb) over a firejail version from Ubuntu. This makes problems, because they are slighlty differently packaged. To install the package you downloaded, first remove firejail and firejail-profiles cleanly from your system and then install the downloaded .deb. But I would recommend to stay with the version provided by Ubuntu and maybe use this PPA to get a newer firejail for your Ubuntu release: https://launchpad.net/~deki/+archive/ubuntu/firejail
