Error while attempting to install apache2 - E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)

Question

When I try to install apache, I have got the following error.

sudo apt-get install apache2

Reading package lists... Done

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 apache2 : Depends: apache2-bin (= 2.4.18-2ubuntu3.13) but it is not going to be installed
           Depends: apache2-utils (>= 2.4) but it is not going to be installed
           Depends: apache2-data (= 2.4.18-2ubuntu3.13) but it is not going to be installed
           Recommends: ssl-cert but it is not going to be installed
 golang-1.6 : Depends: golang-1.6-go (>= 1.6.2-0ubuntu5~16.04.4) but it is not going to be installed
 golang-1.6-doc : Depends: golang-1.6-go but it is not going to be installed
 golang-go : Depends: golang-1.6-go but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I have tried running

sudo apt-get update 

This also did not fix the issue.

Can anyone help me to understand this problem?

Answer 1

Try:

sudo apt-get -f install apache2

Answer 2

I just removed golang completely.

sudo find /var/lib/apt/lists -type f |xargs rm -f >/dev/null

sudo dpkg --remove golang-go

After this, I did update. Then apache2 got installed successfully.
