How can I install a specific gcc or gcc-5-base on a ubuntu 16.04?

Question

I am trying to install libgeos-dev on ubuntu 16.04

This command

apt-get install libgeos-dev

get this error

# apt-get -f install libgeos-dev

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 cpp-5 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.11) but 5.4.0-6ubuntu1~16.04.10 is to be installed
 g++-5 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.11) but 5.4.0-6ubuntu1~16.04.10 is to be installed
 gcc-5 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.11) but 5.4.0-6ubuntu1~16.04.10 is to be installed
 gfortran-5 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.11) but 5.4.0-6ubuntu1~16.04.10 is to be installed

apt-get install gcc-5=5.4.0-6ubuntu1~16.04.11 get the same error as above.

This command

# apt-get install gcc-5=5.4.0-6ubuntu1~16.04.11 \
> gcc-5-base=2.2.20-1ubuntu1~16.04.11

get this error

E: Version '2.2.20-1ubuntu1~16.04.11' for 'gcc-5-base' was not found

this question is different from that post

as I said previously, apt-get -f does not work, and I am work on a CLI server which does not have GUI.

how can I install the dependencies?
