update-manager stopped in the middle, probably because of suspend or sleep (not network down)

[Páll Haraldsson]

Just the facts (I wrote an even longer bug-report and launchpad ate it..):

ubuntu-bug asked if this was related to version update. I said no - should I have said yes? Note, I've used update-manager a few times without this and never happened in 12.04 and older I've used over the years.

[Off topic?: Since maybe this time (I think I was also updating network-manager), WiFi-network shows "no network", still there is network.. not sure if/how it has to do with udev.]

Trying to upload _usr_bin_apt-extracttemplates.0.crash from /var/crash "Only upload I can think of - helpful(?)"

I get this (and probably why first bug-report was eaten.. maybe a worse bug (in launchpad) than this one..):

[Páll Haraldsson (pall-haraldsson)]

Note, I ran update-manager on May 1, since then have had oom as dmesg show, may have had then also, that could have triggered this. Just do not remember or noticed then what was happening. oom are frequent.. Still not sure it happened then. syslog would show, just seems I probably can't upload.. dmesg too old to see? and doesn't show dates.. Why is syslog not uploaded.. by default?
