I tried to install mono-devel and typed sudo apt-get mono-devel in the terminal. But failed and got the following results:
~# apt-get install mono-devel
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
mono-devel : Depends: libgamin0 but it is not installable
Depends: libgnomeui-0 (>= 2.22.0) but it is not installable
Depends: libmono-cil-dev (= 4.2.3.4-0xamarin2) but it is not going to be installed
Recommends: mono-csharp-shell but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried apt-get -f install but still not work. Could anyone help? Thanks!
