First time snapcraft user having issues

[Robert Park]

Fun times, gentlemen:

HOST="/var/lib/snapd/hostfs"

# Break out of snap chroot
if [ -x "$HOST/usr/bin/sudo" ]; then
    app="$(mktemp $HOST/tmp/bileto-app-XXX.sh)"
    $HOST/usr/bin/sudo cp --verbose --force $0 $app
    inchroot="$(echo $app | sed "s#$HOST##")"
    $HOST/usr/bin/sudo $HOST/usr/sbin/chroot $HOST sh $inchroot "$@"
    retval="$?"
    rm --force $app
    exit $retval
fi
