I'm just trying to install Corebird. It has some dependencies and one of them is Gtk+ >= 3.12. I would say I have search a lot and finally frustrated from a lot of other dependencies. I'm afraid if Corebird worth it finally or not!

Is there a straight-forward way to install GTK+ 3.12 on my Ubuntu PC? I mean step-by-step tutorial!

  • The same problems exists in this solution. It just is repeating all other solutions. Compiling gtk+ needs some other packages which I can't find them.

This question has already been answered here. Corebird packages are now available.

If you're on Ubuntu 14.04, open terminal and type:

sudo add-apt-repository ppa:gnome3-team/gnome3

sudo add-apt-repository ppa:gnome3-team/gnome3-staging

Then, for both 14.04 and 14.10 flavours, type:

sudo add-apt-repository ppa:ubuntuhandbook1/corebird

sudo apt-get update

sudo apt-get install corebird

Finally, remove gnome 3 staging ppa:

sudo add-apt-repository -r ppa:gnome3-team/gnome3-staging

source: http://ubuntuhandbook.org/index.php/2014/07/install-corebird-ubuntu-ppa/

  • well done! it works. just why should I remove gnome 3 staging ppa?

  • @Omid If you don't remove gnome3-staging your Software Updater might give you a "partial update" error, which would be hazardous. It is strongly advised not to keep that ppa.

  • Hrm, when installing last step, corebird, I received "The following packages have unmet dependencies: corebird : Depends: libgtk-3-0 (>= 3.11.2) but 3.10.8-0ubuntu1.6 is to be installed E: Unable to correct problems, you have held broken packages." Jun 14, 2018 at 23:40
  • Hrm, seems as if I confused libgtk for gtk+. At any rate, the source link has a comment with the same issue and one suggestion to sudo apt-get install libgtk-3-0 doesn't work as it is still an older version, and "up to date". Jun 14, 2018 at 23:44
  • Actually, I didn't add the gnome3-staging repo. I copied both lines in the beginning but had an error so just tried the first line and forgot to re-run with staging. corebird installed correctly, without having to install libgtk-3-0 since it figured out the dependency correctly.

You can download libgtk3-0-3.12 .deb file ftom Launchpad.net.

Then install that file with the command :

sudo dpkg -i {.DEB FILE NAME HERE]
