[Bug 126775] Re: Update Notifier does not appear after upgrade to Natty

[Jan Reucker]

Found the root cause of my problems... I'm currently running two
installations of 11.04, one on my desktop PC, one on my netbook. Both
didn't notify me of updates, at least I thought so:

1.) On my desktop, update-notifier works correctly, but I didn't
understand the way the user is notified. In the meantime I discovered
that there is no pop-up message or status bar icon. Instead, update-
manager simply starts in the background (minimized to the dock). I had
to get used to this behaviour. The dock is hidden most of the time, so
if you miss the application starting up, you might not notice it.

2.) On my netbook, things were a bit more complicated. Having learned
the new way of notification, I noticed that update-manager starts up
immediately if I 'sudo apt-get update' manually and updates are
available. So the problem wasn't with update-notifier, but with the way
apt updates are performed. Digging through /etc/cron.daily/apt, I found
out that the update is only performed if the computer is on AC power
when anacron runs the script. I usually don't use my netbook on AC
power. Most of the time I charge it and then carry it around running on
battery (that's what netbooks were made for, BTW ;-).

Issue #2 is very annoying for users of portable devices, maybe I'll open
a new bug for it. This behaviour should at least be configurable. With
6+ hours of battery life I don't think it's dangerous to update the apt
database without the AC adapter connected.

Title:
  Update Notifier does not appear after upgrade to Natty

Status in “update-notifier” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: update-notifier

  Although "Update Notifier" is enabled to run at login (I can see this
  from System->Preferences->Sessions), it does not do an automatic
  update, thus, it does not notify me about software updates. I have to
  manually do a "sudo apt-get update && sudo apt-get upgrade" in order
  to have the latest software in my system. I found out that there is
  already a similar bug report at launchpad, but the developers was
  saying that if this bug occurs in Feisty or Gutsy, the bug should be
  reopened. I am using Ubuntu 7.04 Feisty Fawn, so, I reopened the bug
  report (in fact, I made a new one).
