The above error is due to the fact that gtk-keyring package is not installed correctly.
As you can see, it’s not installed correctly.
The problem is that it’s not installed using apt-get. The first thing that should be done is to check if you have the right repository.
In order to install a package with apt-get, you need to have the main repository enabled, and the key for that repo enabled. If you don’t have the repo enabled, then you will get the above error message.
For the sake of completeness, it should be noted that there are several packages that have a gtk-keyring dependency that is not installed properly. The problem is that while these packages are installed by default, they are not used. The packages that are not installed properly are: gtk-cairo, gtk-engines, gtk-image-viewer, gtk-indicate, gtk-keysyms.
