I'm having trouble with running a script to install prerequisite packages, which requires gcc-4.6-base:i386, and don't know how to install it with aptitude or something similar. For reference, I'm currently running Ubuntu 5.4.0-6ubuntu1~16.04.2. The error messages I'm getting are:
E: Unable to locate package gcc-4.6-base:i386
E: Couldn't find any package by glob 'gcc-4.6-base'
E: Couldn't find any package by regex 'gcc-4.6-base'
It looks like the binary package can be found here. Furthermore, I've tried this out but to no avail. I've also done multiple rounds of sudo apt-get update and sudo apt-get install. For reference, this is an Ardupilot project and I'm following along here, getting stuck on running the script Tools/scripts/install-prereqs-ubuntu.sh -y.
Any and all help appreciated, and I'd be happy to provide more info if need be. Thanks!
