GCC-Multilib

Hi everybody.

I'm trying to install Feral's gamemode 32-bit libraries, but it needs some 32-bit libraries which are included in gcc-multilib package, which is not installable on Trisquel.

vanacksabbadium@Cyclops:~/Desktop/gamemode/build32$ sudo apt install gcc-multilib

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:
gcc-multilib : Depends: gcc-5-multilib (>= 5.3.1-3~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Is there something i can do?
Thank you in advance.
