Doesn't check for updates when connection becomes available

[Alexander Sack]

During the https://blueprints.launchpad.net/ubuntu/+spec/jaunty-desktop-network-changing blueprint discussions it was identified that update-manager lacks a proper integration: it should trigger update of Packages list when network-manager becomes available.

<https://wiki.ubuntu.com/SoftwareUpdates#check-automatic>: "Once it is due to check for updates, it should try to check one minute after the first time any administrator connects to the Internet."

(This bug report originally also covered discouraging updates on mobile broadband, now reported as bug 776374. See also bug 272131.)

jaunty spec -> importance high.

[Steve Langasek (vorlon)]

I'm assuming since there's been no activity on this bug that the code changes are not yet done and available anywhere, so I'm marking this wontfix for jaunty. Ping me if you disagree.

Seems that milestone is in the past.

[Matthew Paul Thomas (mpt)]

#1 and #2 probably should be split into separate bug reports.

Precise software-properties are set to daily, screenshots of dconf settings are there, bug 913325.
Diff of dconf apps.update-manager Oneiric launch-time: 1327069527 and Precise: 1327222860.
Diff of dconf com.ubuntu.update-notifier Oneiric release-check-time: 1326913693 and Precise: 1326748631.

Those numbers haven't been manually changed by user. Oneiric was a desktop upgrade, Precise a fresh installation on laptop.

Online now since about half an hour, nowhere an indication of updates available.

After 41 min. online apt-xapi runs and update-manager is up in launcher.

Oneiric displays updates available after about 43 min. (without running firefox, if that's relevant).

[Sam_ (and-sam)]

Kernel -14 and others landed, but no indication after 1:30h uptime.

[Sam_ (and-sam)]

Availability improved. On laptop and pc (both up-to-date Precise) update-manager appears after 10 - 20 min. online. Availability seems to occur faster when firefox is up.
