/bin/udevadm should be exit 0 instead of exit 1

[Onno]

if [ "$1" = "trigger" ]; then
echo "some text halt was sinnvolle oder unsinniges zum Abruch
          exit 1
fi

apt-get install rfkill
for example fails to configure

why not in /bin/udevadm end with exit 0 in case of trigger
or settle?

then apt-get install rfkill and 28 other packages can configure

This seems to have nothing to do with the Ubuntu Packaging Guide. Can you file a bug on Ubuntu instead? https://help.ubuntu.com/community/ReportingBugs

Ok in lynx I don't see that. You can't move this bug? It is terrible
with no working X oben a bug with lynx.

So you're saying this is a problem in the rfkill Ubuntu package? Can you try to explain the issue a bit more? Which behaviour are you seeing? What did you expect? Which version of Ubuntu are you using?

[Onno (schiller-babsi)]

No, I am saying it is a bug in serveral package or in udevadm. All
packages, which call /bin/udevadm trigger or /bin/udevadm settle get a
Sigkill.

Solution change udevadm or change packages if xenial change udevadm - rfkill is just an example there are more packages, which call /bin/udevadm at dpkg configure ... if you change udevadm, then

cat udevadm
#!/bin/sh

if [ "$1" = "trigger" ]; then
    echo "udevadm trigger is not permitted while udev is unconfigured." 1>&2
    exit 0
fi

if [ "$1" = "settle" ]; then
    echo "udevadm settle is not permitted while udev is unconfigured." 1>&2
    exit 0
fi

exec /bin/bash -c "exec -a \"\$0\" /bin/udevadm.upgrade \"\$@\"" "$0" "$@"

then
dpkg --configure -a
rfkill (0.5-1ubuntu3) wird eingerichtet ...
udevadm trigger is not permitted while udev is unconfigured.

but get configured, because the package didn't get a sigkill
