[Bug 1033226] Re: No close option, only restart

[Matthew Paul Thomas]

thedanyes, I think your hypothetical is addressed by my previous
comment. If Ubuntu becomes extremely popular, and the proportion of
people who delay restarting becomes a substantial security problem, it
may indeed become necessary to "force" restarting, by changing the
"Install" button to "Install and Restart" -- which, if clicked, logs out
to a special session where Software Updater is the only thing running
and it restarts when done. But for now at least, we aren't doing that.

Anyway, I've completed the design for this.
<https://wiki.ubuntu.com/SoftwareUpdates?action=diff&rev2=101&rev1=100>
A fair bit of work will be involved in keeping it all looking simple,
but this is a summary of the changes required:

1. Software Updater should launch automatically not just when it has
been 24 hours since you were last reminded that security updates were
available, but also 24 hours since you were last reminded to restart to
finish installing security updates. The reason is exactly the same in
both cases; as long as the installation isn't finished, you aren't
secure. And analogously for non-security updates with the non-security
update interval.

2. The restart-required alert should have a "Restart Later" button.
Hooray!

3. If updates are available *and* a restart is required to install
previous updates, the latter should be shown with secondary text in the
updates alert.

4. If updates are available and a restart is required to install both
these updates *and* previous updates, we shouldn't bother with the "The
computer will need to restart" text, because the computer already does
need to restart.

5. When installation completes (whether successfully or unsuccessfully),
Software Updater should generally behave as if you have just launched it
manually -- showing whether updates are (still) waiting to be installed,
a restart is required, both, or neither. This should simplify the code a
bit.

  where is my restart later or close option?

  This is a big usability bug!
