[Bug 1007924] Re: pm-utils uses wrong interface for NetworkManager hook (should be org.freedesktop.NetworkManager.Sleep)

[Andreas Mohr]

Can we PLEASE get this resolved very soonish, in an important LTS
version, of all things holy?

It took me ages (~1h) to figure out the exact reason for use of an illegal(!!) stale dhclient DHCP lease IP after suspend / resume / hibernate via Internet research (which keywords would YOU use to discover sufficiently relevant topics? they all seem to fail...),
and according to my log that is exactly the problem here on 12.04LTS:

(as currently executed by /usr/lib/pm-utils/sleep.d/55NetworkManager of pm-utils 1.4.1-9fix.ubuntu12.04)
# dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.sleep
Error org.freedesktop.DBus.Error.UnknownMethod: Method "sleep" with signature "" on interface "org.freedesktop.NetworkManager" doesn't exist

(corrected syntax as suggested by this report, working!)
# dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Sleep boolean:true
method return sender=:1.5 -> dest=:1.972 reply_serial=2

# dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager
/org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Sleep
boolean:false

This report of a CRUCIAL suspend/resume breakage bug (my usual keyword
for such annoyingly frequent cases: "YASB") on a LONG-TERM-SUPPORT
distro is now more than THREE years old (fdo report), with a confirmed
working solution that is now 1.5 YEARS old. Please do (or communicate
some suggestions) what is necessary to finally have this high-profile
illegal-behaviour SHOW-STOPPER bug get resolved. Thank you. [I somehow
hate having to spell things out that clearly, but... anyway, please
accept my apologies]
