status: New → Confirmed

time-admin requires synaptic and gksudo to install the ntp package, but Xubuntu does not ship these programs by default anymore.

Affecting me after a clean install of the 14.04 b1. Per discussion on #xubuntu-devel, running the following from the command line works, but may not be the ideal solution: pkexec --user root apt-get install ntp -y

clean install.

sudo apt-get install ntp

_did_ work for me.

ntp is overkill. ntpdate is all that *should* be required.

Really nice that the LTS Ubuntu does not support NTP any more ...

manually installing ntp helped, but it should be simpler than that.

How is the debugging going, Alistair? You assigned the bug to yourself, but it's been 9 months since the assignment without any information.

The bug is still present in 14.04.1. I did a fresh install yesterday, and I still can't install ntp support.

Sorry I forgot about this. Here's a debdiff which should fix it. It will need cleaning up and testing.

Alistair Buxton (a-j-buxton) wrote :

What this does is replace all the synaptic and gksudo code with a dbus call to packagekit. The old code was added in an Ubuntu patch, so I just regenerated that patch with the new code instead. I don't know if that is the correct way to do it. Only one file needs to be modified, gst-package.c. The new version of 80_gst-packages-common.patch is generated with different diff options so the diff is kind of confusing, sorry about that.

The packagekit source is taken almost verbatim from the C example here: http://www.freedesktop.org/software/PackageKit/pk-faq.html#session-methods

The attachment "Fix typo on my email address" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

It seems like this would possibly be a good candidate for SRU; but this requires that the bug be also fixed in the development release. Given that there's already a tag for utopic and reports that it doesn't work there, I suspect it also doesn't work yet in Vivid.

Alistair, maybe you'd be interested in also preparing the patch for vivid?

Finally; please see https://wiki.ubuntu.com/StableReleaseUpdates#Procedure; there are some more tasks needed before we can SRU this (updating the description according to the SRU bug template in the link). I'll unsubscribe sponsors for now, but feel free to re-subscribe the team once you have patches ready for the development release as well.

This broke in the first place because gksudo was removed from the default distribution. So it is broken in all recent releases.

I would do the patch for Vivid if I knew how.

This bug was fixed in the package gnome-system-tools - 3.0.0-4ubuntu2

gnome-system-tools (3.0.0-4ubuntu2) vivid; urgency=medium

  * debian/patches/80_gst-packages-common.patch: rework to use PackageKit
    to download any required packages; since there is neither gksudo nor
    synaptic available anymore on default installs. Thanks to Alistair Buxton
    for the patch. (LP: #1270090)
  * debian/control: Recommends python3-aptdaemon.pkcompat | packagekit, so that
    we make sure some form of packagekit API is available to get the package
    installation requests if possible.
