To do this I’ve added traceroute to the stage-packages: line in my snapcraft.yaml. The files to get put into the; /snap/openswitch-appliance/x1/… $SNAP tree and indeed I can then see them from inside the SNAP. root@Snappy-Appliance:/home/netop# find $SNAP -name "traceroute*" /snap/openswitch-appliance/x1/usr/bin/traceroute-nanog /snap/openswitch-appliance/x1/usr/bin/traceroute.db /snap/openswitch-appliance/x1/usr/bin/traceroute6.db /snap/openswitch-appliance/x1/usr/share/doc/traceroute /snap/openswitch-appliance/x1/usr/share/man/man1/traceroute-nanog.1.gz /snap/openswitch-appliance/x1/usr/share/man/man1/traceroute.db.1.gz /snap/openswitch-appliance/x1/usr/share/man/man1/traceroute6.db.1.gz But the problem is that the installation isn’t properly finished because the the postinst stage didn’t get run. If you look at the postinst stage for the traceroute package you’ll see what I’ve listed below. In other words for this package to work it is meant to build some softlinks to /etc so that “traceroute” is actually made available. How am I meant to do this is the SNAP world? </div> </blockquote> Hey Dave, Looking at the postinst, it doesn't seem this is actually that you need to execute any postinst in this specific case. The update-alternative calls here are just to make available a default "traceroute" binary pointing to your "usr/bin/traceroute.db" (same for manual page). You can expose it directly through apps to get the same result: apps: traceroute: command: $SNAP/usr/bin/traceroute.db If the issue is that other commands from this package are using "traceroute" internally, you can ship a symlink yourself that you ensure are in your $PATH snap.
