[SOLVED] PgAdmin: Package 'pgAdmin4' has no installation candidate

Issue

I just installed PostgreSQL and I am trying to install pgdmin4, but whenever I run the command below to install pgadmin4 and pgadmin4-apache2

sudo apt install pgadmin4 pgadmin4-apache2

I often get the error

E: Package 'pgadmin4' has no installation candidate

E: Unable to locate package pgadmin4-apache2

I have tried out a lot of solutions, but none seems to do the trick. I need some help.

Solution

Here's how I solved the issue;

The issue arises because the repository for pgadmin has not been added to your local machine. To solve the issue, do the following below;

Note: This should work in Ubuntu 16.04 (Xenial), Ubuntu 18.04 (Bionic), Ubuntu 19.10 (Eoan), Ubuntu 20.04 (Focal), Debian 9 (Stretch) and Debian 10 (Buster)

Install the public key for the repository (if not done previously):

curl https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo apt-key add

Create the repository configuration file:

sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'

Choose the Installation method that you want:

• Install pgAdmin (for both desktop and web modes):

  sudo apt install pgadmin4
  

• Install pgAdmin (for desktop mode only):

  sudo apt install pgadmin4-desktop
  

• Install pgAdmin (for web mode only):

  sudo apt install pgadmin4-web 
  

You can configure the webserver, if you installed pgadmin for web mode:

sudo /usr/pgadmin4/bin/setup-web.sh

Resources: pgAdmin 4 (APT)

That's all.

I hope this helps.
