After reading that question I realise I need to install supervisor.

sudo apt-get install supervisor tells me: 

E: Unable to locate package supervisor

sudo apt-cache search supervisor gives nothing.

Also when I look at other questions it seems that it is installed by default in Ubuntu 16.04.

I am using Ubuntu 16.04 LTS.

Why can't I find this package? How can I install it?

I also looked at install recommendation on official doc of supervisor but I would prefer to use the distribution package solution.

Looking at the package in the 16.04 repository, it seems that it is in the "Universe" repository.

So, you first need to enable it:

sudo add-apt-repository universe

Then you can actually install the package:

sudo apt-get update
sudo apt-get install supervisor

  • thanks for your input @Android Dev but I've hit another wall: the `add-apt-repository universe` creates `/etc/apt/sources.list` that contains a single lign: `deb http://archive.ubuntu.com/ubuntu xenial universe`. And the command `add-apt-repository universe` returns: `WARNING:root:could not open file '/etc/apt/sources.list'` + `'universe' distribution component enabled for all sources.`. `apt-get install supervisor` does not work after `apt-get update`. I look to understand the difference between /etc/apt/source.list and /etc/apt/source.list.d and it does not seems that it could be an issue. – nyluje Apr 11 '17 at 09:13
  • Something is wrong with the installation. `/etc/apt/sources.list` should be there. It seems that it is some customized installation with some restrictions. – Pilot6 Apr 11 '17 at 09:20
  • I had another issue linked to disk occupation. I fixed that and the answer provided works. – nyluje Apr 11 '17 at 16:28
