I've been trying to update standard packages on my Ubuntu box. There's literally nothing extra on this box except for VirtualBox for some Windows stuff I run. Here's one output:
$ sudo apt-get update [...] $ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: libgail-3-0 : Depends: libgtk-3-0 (= 3.6.0-0ubuntu3.2) but 3.6.0-0ubuntu3.1 is installed libgtk-3-0 : Depends: libgtk-3-common (= 3.6.0-0ubuntu3.1) but 3.6.0-0ubuntu3.2 is installed libgtk-3-bin : Depends: libgtk-3-0 (>= 3.6.0-0ubuntu3.2) but 3.6.0-0ubuntu3.1 is installed And another with the -f option:

I've also tried sudo apt-get -f install, sudo apt-get dist-upgrade and sudo apt-get clean && sudo rm -r /var/cache/apt/archives/, but all lead to the same error.

Ok, if you are still experiencing this problem, it happens because some package won't work if the versions of their peers aren't the same.
libgail-3-0 : Depends: libgtk-3-0 (= 3.6.0-0ubuntu3.2) but 3.6.0-0ubuntu3.1 is installed libgtk-3-0 : Depends: libgtk-3-common (= 3.6.0-0ubuntu3.1) but 3.6.0-0ubuntu3.2 is installed libgtk-3-bin : Depends: libgtk-3-0 (>= 3.6.0-0ubuntu3.2) but 3.6.0-0ubuntu3.1 is installed As you can see libgail-3-0 requires libgtk-3-0 to be 3.6.0-0ubuntu3.2 but libgtk-3-0 requires libgtk-3-common to be 3.6.0-0ubuntu3.1 a diference of .1 versions. So, since libgtk-family can't be of different versions, apt-get gets an expectacular dependency error. So how to solve this? We use the hold package status:
echo "libgtk-3-bin hold" | sudo dpkg --set-selections echo "libgtk-3-0 hold" | sudo dpkg --set-selections With this, you can upgrade normally until the dependency conflicts get resolved in the Ubuntu repositories.
Once you feel that you can allow upgrades, just run:
echo "libgtk-3-bin install" | sudo dpkg --set-selections echo "libgtk-3-0 install" | sudo dpkg --set-selections Another option is to force versions to being installed:
sudo apt-get update sudo apt-get install libgtk-3-0=3.6.0-0ubuntu3.1 libgtk-3-common=3.6.0-0ubuntu3.1 libgtk-3-0=3.6.0-0ubuntu3.1 This will tell apt-get to install everything using the same version number.
For anyone who still has those problems.
I believe they appear when you manually delete some packages but don't clean all the rubbish they leave behind. In my case I had libgtk still installed and it was a newer version then I wanted to install. So it really didn't know what to do with different versions of the library.
After just deleting the libgtk-3-0 and other packages with similar problems everything went on fine.
PS. Note that if you have done echo "libgtk-3-0 hold" | sudo dpkg --set-selections Then you HAVE to do echo "libgtk-3-0 install" | sudo dpkg --set-selections in order to be able to delete this package.
