[Martin McDowell]

There still don't seem to be any improvements on this functionality,
including the "disable" option on this annoying warning. I am running
10.04 and the update-manager is in version 0.134.8

But even then, there should be an option to turn this warning off.
(a tick "do not show this anymore" or something in software sources options)

The warning was introduced at an inappropriate place: it should appear
when you choose to install updates, not when Update Manager opens in the
first place.

This will be fixed in a forthcoming redesign of Update Manager.

Any chance of an option in preferences to hide the irritating
confirmation box that has resulted from this paprcut for those of us
that don't have soap suds for brains and are well aware that our
netbooks are running on the battery?

[Bug 377697] Re: update manager should warn about laptop running on battery when installing big updates

[luke2760]

I just had my machine enter suspend while I was running the Karmic
upgrade. This is a brand new machine, and I copied ~/ over from my old
machine in 9.04, then started a distribution upgrade via update-manager.
Came back a couple hours later and it had suspended. Is distribution
upgrade separate from update-manager? Does it inhibit suspend?

I know this bug is closed, but can the wording on this notification be
changed? Right now the user is notified that they are running on
battery, but are not told what the dangers are if the battery runs out.

Michael and I just discussed this, and decided that it shouldn't affect
the auto-opening behavior, because that would mean people who only ever
use a computer while it's on battery (and charge it while it's
suspended/off) would never be notified.

This sounds like we also should not auto open update-manager if the
system is running on battery.

[Bug 377697] Re: update manager should warn about laptop running on battery when installing big updates

[d3mia7]

Further to this it may be wise to look at how Update-Manager interacts
with power management.  When Update Manager is active, it prevents the
system from entering 'Suspend'.

I can understand this - say the updates being applied could potentially
prevent suspend from working.  However it actually makes this paper cut
much more severe since you can wind up in a state where you started an
upgrade, ran out of power and then couldn't even suspend and resume
later to complete it!

Searching for updates while on battery power in the first place sounds
like a bad idea to me.

[Bug 377697] Re: update manager should warn about laptop running on battery when installing big updates

[Peter Cordes]

That's a good idea.  It might be good if this was at a low enough level
in apt that aptitude, and even apt-get, could prompt, too.  (or just
warn if non-interactive).

 Download speed is very hard to predict, and could take a _really_ long
time.  So it would be smart to check battery status after download but
before install.  Alway warn at that point if you're on batteries, but if
there is lots of battery left and few updates, don't hold up the process
by waiting for user input.

 A good heuristic might be:  Get time until battery-critical shutdown
(from ACPI on PC hardware...).  Estimate update install time very
conservatively (in case of slow discs and/or competing I/O load) as 5s
per package + 10s per uncompressed MB.  (made-up numbers, not based on
any measurements.)  Some packages have time-consuming post-install
scripts; another reason for a conservative estimate.

  If install time > (battery - 10min), wait for user confirmation.  This
is after download.  But always warn when on battery before starting to
download, in case the user goes away right after starting the download.

 The extra heuristics for forcing user confirmation before actually
installing when on battery may be excessive, but a forced shutdown
during an update could cause a really big problem.  (most laptops
support suspend or hibernate, but some may resort to shutdown -h now.)
