I'm using Ubuntu 14.04. I'm trying to download postgresql using this guide.

But when I run the command sudo apt-get install postgresql-9.4 in my terminal, I get this error message:

E: Unable to locate package postgresql-9.4
E: Couldn't find any package by regex 'postgresql-9.4'

What am I doing wrong?


You can install postgres 9.4 on Ubuntu 14.04!

Follow the instructions on http://www.postgresql.org/download/linux/ubuntu/:

Create the file /etc/apt/sources.list.d/pgdg.list, and add a line for the repository:

deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main

Import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | \
  sudo apt-key add -
sudo apt-get update

Now you can install with

sudo apt-get install postgresql-9.4

    @noogui literally just copy paste the above in your terminal. To "create the file" just type sudo touch /etc/apt/sources.list.d/pgdg.list or use a program like vim, nano, or emacs. In that file youve created, just add the one single line starting with deb - that is the location of the postgres package repository. Then just copy the rest of the commands above and paste it into your terminal - it will add the authentication key for your system and that repository. Run the final command above to install the 9.4 package from the repository.

  • This should be the accepted answer, helps users on other platforms such as Debian or other versions of Ubuntu altogether. Nov 20 '19 at 13:46

That is because in Ubuntu 14.04 repositories there is postgresql-9.3 version. So run

sudo apt-get install postgresql-9.3
  • I got back "E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)."

  • So run "sudo apt-get install -f".

  • Not "sudo apt-get -f install"?

    So what if you want to use the 9.4 version, which actually have the functionality (jsonb) that I need?
