Hi there
A few weeks (months?) back I upgraded my parents system to 13.04,
they were quite scared of doing it themselves so they asked me to
do it (which is weird since they have done the process already).
So I found this on the systemtray:
http://wstaw.org/m/2013/06/17/instant%C3%A1nea5_png_750x750_q85.jpg
First I clicked on the bulb since it is the most different icon. I
tasked me to "Run this action". I did. A terminal opened with some
text that since I was distracted I was not able to see. Once it
finished the bulb appeared again in what seemed to be an infinite
loop of "Run this action", "Terminal Opens", "Bulb appears again".
this issue is really really really weird. so the bulb essentially
represent an ubuntu feature called package hooks. it allows a package
to let the user execute a command after installation/upgrade. this is
to move time consuming or complex configuration out of the installation.
most prominent example is apt-file, which requires a file cache of all
packages available through apt, creating that cache takes ages and
requires an active internet connection so someone moved it into a
hook. this allows the user to create/update the cache after
installation when he does not intend to use the system and has
internet available.
a hook needs to explicitly declare that it wants a terminal to be
shown making it very much a packagers' choice. you could have a gui
application 'myconfig' run via the hook as well, allowing the user to
do indepth configuration of mysql or something without ever showing a
terminal.
all that said, the only reason you'd get this behavior is by having a
very weird package installed (i.e. there are very few archive packages
using this and really only apt-file comes to mind) or the notifier
kded module is/was bugged.
Looks like flashplugin-installer uses this hook and requires terminal as
well (it downloads actual flash from Canonical's server there and then
actually installs it), as i always get this behavior when flash is updated.
you could take a look at /var/lib/update-notifier/user.d/ to see what
files linger there.
Then I clicked the white update icon I think, muon-updater was
executed I selected all packages when it was suggested that a new
version was available but I decided to upgrade the current version
first. The process failed because it was unable to download some
packages.
I am not sure whether that was fixed meanwhile... Jonathan? I have
been complaining about this for years :P
What happens is that apt-get update is run -> notifier is shown ->
user waits 3000 days -> clicks notifier -> tries to install -> 404
parade (though I have to admit this only happens with PPAs, the
official archive does not remove packages). Easy as hell to resolve by
simply forcing a cache update before starting the actual package
installations.
this really should not ever happen. in fact, updates should not ever
fail for no reason what so ever, not even if the internet connection
is lost the flipping update should fail but be put on hold or
something. I know, I am day dreaming again... :(
Then I clicked the other button, the dialog that appeared was not
fully translated to Spanish (this would be important to my parents).
was it this here thingy?

I do admit that I have not ever looked at upgrade l10n as that is
supposed to be shared with the gnome tool, so it should work(tm) -.-
Once the upgraded finished and I rebooted the computer, I found
again two icons on the systemtray, this time only the colored
upgrade and the bulb.
I clicked the bulb, then "Run this action", then a terminal
opened, and the bulb was finally gone.
I clicked on the colored icon, muon-updated appeared, upgraded
some packages and offered me restart.
this is curious. Jonathan, isn't muon-updater supposed to be the
monochrome icon? :O
How can we improve this? what is this bulb doing? can it stop
showing a terminal?
Can we only show one icon instead of 2 for upgrade?
my best guess for this is that one was the dist-upgrade and one was
the muon-upgrader for regular packages. Jonathan would know.
supposedly it should be still be the same notifier though (perhaps
simply use a different icon if a dist-upgrade is available?). upon
clicking it muon-updater comes up and presents both options.
Why did I have to upgrade just after upgrading? I had bad luck or
is it normal?
bad luck most likely. though some time ago we discussed the
possibility of phasing non-security updates - such that updates only
get offered every 7 days by default - it would prevent this type of
experience fail.
I really think we eventually should sit down and fix the
update/upgrade/dist-upgrade experience there are many of these minor
issues that at least to me pretty much wreck the experience (not that
anyone likes doing upgrades anyway, but at least we should make them
less awkward ;)).
