Unable to Install Cockpit on Bionic

I am trying to install cockpitvby using apt-get install cockpit but getting following error.

apt-get install cockpit

The following packages have unmet dependencies:
cockpit : Depends: cockpit-system (= 172-1~ubuntu18.04.1) but it is not going to be installed
Recommends: cockpit-storaged (= 172-1~ubuntu18.04.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


With little bit of googling and cockpit instruction from Ubuntu,I also added following line to source.list

source.list

deb http://archive.ubuntu.com/ubuntu bionic-backports main restricted universe multiverse


as outlined in Ubuntu help, then updated

sudo apt-get update


and then try installing

sudo apt-get install cockpit


But still getting following error:

The following packages have unmet dependencies:

Recommends: cockpit-storaged (= 172-1~ubuntu18.04.1) but it is not going to be installed

Please note that cockpit exists in the official repository of Bionic so to install simply do:

sudo apt update && sudo apt install cockpit


Note: Remove those repos you added and the update via sudo apt update and proceed to install.

sudo apt update

After due interaction with OP I discovered that the problem was he lacked the universe repos in sources.list so to overcome we followed this steps:

universe

sources.list

Add repo:

sudo add-apt-repository universe


update accordingly:

sudo apt update


Now install:

sudo apt install cockpit
