[Bug 1046563] Re: update-manager never appears on lubuntu precise

[sde]

This is a workaround for apparently the same problem as Scott Cowles
Jacobs, not receiving automatic update notifications in Lubuntu 13.10

I didn't get updates for a few weeks (last auto update 9 December 2013,
after 8 December 2014 update-notifier was updated, until I manually
updated about 4 January 2014.)

So I put this line in Preferences > Default applications for LXSession >
Autostart > + Add

@/usr/bin/update-notifier

That line is added to ~/.config/lxsession/Lubuntu/autostart (so it could
also be added by editing that autostart file directly.)

I used the line, ``$ ps -ef | grep "update" `` in LXTerminal to check
that update-notifier wasn't running at first, and that it could run as a
background process using the command ``$ update-notifier & `` and that
it was running after I added it to autostart and restarted.

Doing just that didn't seem to work, because there were updates waiting
when I checked by manually starting Software Updater after a day.

So I also installed python3-aptdaemon-pkcompat because it was on the
"missing recommends" list, although I didn't know if that was correct to
do, because installing that using Synaptic causes packagekit to be
removed, which seems like it might defeat the purpose of having
PackageKit compatibility in Python 3. (The situation of having to choose
which of those packages to have installed, with both being recommended
but not both allowed, seems to have started after I installed a Gnome 3
desktop environment then uninstalled it back when I was using
Ubuntu+Lubuntu 13.04 before I upgraded Ubuntu+Lubuntu to 13.10.)

After I had my system set up that way for over a day, I finally got my
first automatic update notification in a month.

The package update-notifier has some Python 3 files in it, and runs as a
daemon and gets messages resulting from a file in etc/cron.daily named
apt, according to some of the read me information in the update-notifier
complete package, so maybe it helps to have python3-aptdaemon-pkcompat
installed. Maybe packagekit is just a different frontend of the actual
PackageKit system that doesn't matter unless certain applications are
calling it to get updates that are specific to those applications.

This is just a workaround. I haven't found a configuration file that
would cause Lubuntu to run update-notifier normally. On the list of
programs to start at startup in Desktop Session Settings, Update
Notifier is checked, but I don't know if it should be or what effect
that checkmark has.

Title:
  update-manager never appears on lubuntu precise

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  i have upgraded to 12.04.1 and I've recently noticed that update-
  manager no longer prompts to install updates.  Previous to 12.04.1, it
  was mostly popping up every day.

  To reproduce, run the cron script and see if update-manager comes up,
  which it won't.

  to fix the bug, update-manager should show updates when they are
  available.

  I believe that update-manager works properly on a default install of
  lubuntu 12.04.  however, once it runs and updates to the new update
  manager, update manager turns itself off.
