I have a docker container running debian linux (it's using the postgres image) that I'd like to install nano on so I can edit files. However, when I try

# apt-get install nano

the output I get is

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package nano

I am following this documentation. What step am I missing here?


So apparently there was an easy solution to this. I just needed to update first:

# apt-get update
# apt-get install nano
  • Please, say, why before "apt-get install nano" you should do "apt-get update"? – Viktar Akulenka Apr 20 '20 at 13:30
