Ok, this is the correction, so from where exactly is gcc-5-base
5.4.1-2ubuntu1~14.04?

"Package: gcc-5-base (5.4.0-6ubuntu1~16.04.2 and others) [security]"
- http://packages.ubuntu.com/xenial/gcc-5-base

"Package: gcc-5-base (5.4.0-6ubuntu1~16.04.2)"
- http://packages.ubuntu.com/xenial-updates/gcc-5-base

Regarding http://packages.ubuntu.com/ for trusty no package named
gcc-5-base is available at all.
