I'm trying to get the "traceroute" package to install properly inside my SNAP.
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?
Thanks,
Dave Garrod
