I can't install synaptic package manager in Ubuntu 16.04.
I do this:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install synaptic

And I see

Package synaptic is not available, but is referred to by another package. 
This may mean that the package is missing, has been obsoleted, or is only 
available from another source 
E: Package 'synaptic' has no installation candidate

What can I do?

The output of sudo apt update command:

Hit:1 http://archive.canonical.com xenial InRelease
Hit:2 http://archive.canonical.com/ubuntu xenial InRelease

Go to System Settings -> Software and Updates and check the "universe" repository.

You can also enable "multiverse" and "restricted" too.

Then the package will get installed after sudo apt update.

Normally these repositories are enabled by default in installed systems, but are disabled in Live systems. In your case the repositries are not enabled for some reason.

  • Did you install synaptic successfully? If yes, then please accept this answer by clicking the check sign at the left. Regarding Skype you can ask another question, or find a solution yourself. Tip: you will need to enable "Canonical Partners" repository on "Other Software" tab. – Pilot6 Jan 22 '17 at 11:01
