I have installed language-selector-gnome 0.129.1 from trusty-proposed
and - unlike before - when logged in as a standard user, the buttons in
question are sensitive and I'm able to make system wide changes if
providing an admin password.

Hello Philipp, or anyone else affected,
Accepted language-selector into trusty-proposed. The package will build
now and be available at http://launchpad.net/ubuntu/+source/language-
selector/0.129.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package.
Hi Philipp!
Right, the language-selector UI will live longer than we thought, and
nothing has happened with Martin's freedesktop bug about PolicyKit. I
have made a change that I think is a reasonable way to deal with this
issue. You won't be prompted to install possible missing language
support

Now the S development cycle has passed, and I installed Ubuntu 14.04 and
there is still the same dialog, and it has still the same problem. Is
there now a chance that this gets revisited?

Philipp,
Maybe the solution you propose is easy to implement if you know how to do it. I
for one don't. Please feel free to provide code.
The language-selector UI is planned to be replaced in the standard
Ubuntu distribution by the corresponding UI in gnome-control-center. It
will probably
I'm disinclined to propose that the is_admin check is dropped, since it
would degenerate the UI for a lot of (non-admin) users. I think that the
check for missing langpacks would make that route especially bad, and
personally I'd prefer to leave the bug open for the time being.

Martin, what's your estimate of how long it will take before the polkit
people deal with your bug?
Really hard to say, it depends on the available time and mood of the
polkit authors. Could be anything from a few days to many weeks; we

Please, drop the is_admin check completely.
I said it already: you cannot know whether the user knows the password
of an admin account if you do not ask for it. If you try guessing, you
will inevitable guess wrong sometimes and frustrate the user. This is
also true if polkit does the guessing.
Thanks, Martin. Unfortunately I can't reproduce your Not authorized.

I previously just tried this under su, but I fell into the trap that

I filed an upstream polkit bug to get access to this information, as
this is IMHO the only clean way of fixing this. Until then, I suggest to

The problem is that polkit responds with no, but you can
authenticate (or something like it) also for standard users.
Hm, I get a different error message depending whether or not the user is
an admin:
for my user (which is an admin):
$ pkcheck --action-id
Trying to summarize the suggestions so far:
* Ask polkit
I failed to make polkit provide the info we would need. If somebody knows how
to do that, it would probably be the best and easiest solution. The code in the
linked branch may or may not be useful as a starting point.
* Drop the is_admin
I would get rid of greying out these buttons completely.
You will never know whether the user is able to authenticate as admin,
because you cannot know whether the user knows the password of an admin
account if you do not ask for it. In all cases where the buttons are
greyed out, but the user
philw85: I completely agree. The time settings dialog is a great example
for how this should work.
I think it's also fine to just let PolicyKit prompt when it needs to
without telling the user beforehand. Average Ubuntu users are going to
be admins on their single-user systems, and where users

Yes, it is. That's how polkit works
If we can't make polkit provide the desired information without real
authentication attempts, and since this is a GUI issue and not a
security issue, maybe a gsettings key could be a sufficient solution to
this bug.

This is possible. The polkit API has a flag to enable/disable
interactivity, depending on which you either get a no, but you can
authenticate, or a yes

Thanks for the hints, Martin. I gave up on ls-dbus-backend, discovered
gir1.2-polkit-1.0 and wrote a new function in utils.py. Now the code
runs, but there is a tiny problem: AdminPrivileges() always returns
True. :(

I'm not sure why this doesn't work, as other parts of the code do the
same. However, this is not what you want anyway: This check would
already authenticate, i. e. you would get a password prompt right at the
startup of l-s just for checking if you are an administrator. Instead,
this should query

I linked an experimental branch to this bug, where I show a first
attempt to change language-selector in this respect. It doesn't work,
though.
