pgAdmin is an open-source, powerful, and feature-rich graphical user interface (GUI) administration and management tool for the PostgreSQL database. Currently, it supports PostgreSQL 9.2 or later, and runs on Unix and its variants such as Linux, Mac OS X as well as Windows operating systems.
It provides a powerful user interface that enables you to easily create, manage, maintain and use database objects, by both beginners and experienced Postgres users alike.
In this article, we will show you how to install pgAdmin 4 on Debian 10 system to provide secure, remote access to PostgreSQL databases.
This guide assumes that you already have PostgreSQL 9.2 or higher installed and configured on your Debian 10 server, otherwise to install it, follow our guide: How to Install PostgreSQL 11 on Debian 10.
Installing pgAdmin 4 in Debian 10
Debian 10 ships with pgAdmin 3 by default. To install pgAdmin 4, you need to enable the PostgreSQL Global Development Group (PGDG) APT repository (which contains PostgreSQL packages for Debian and Ubuntu) on your system.
# apt-get install curl ca-certificates gnupg # curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
Then create a repository file called /etc/apt/sources.list.d/pgdg.list.
# vim /etc/apt/sources.list.d/pgdg.list
And add the following line in the file.
deb http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main
Save the changes and exit the file.
Now update the APT package cache (which is a mandatory step), and install the pgAdmin 4 package as follows. The pgadmin4-apache2 package is the WSGI application.
# apt-get update # apt-get install pgadmin4 pgadmin4-apache2
During the package installation, you will be asked to set an email address for the pgAdmin web interface initial user account. This email will work as the account name, provide it and press Enter.
You will also be asked to set a password for the pgadmin4 initial user account. Provide a secure and strong password, then click Enter to proceed.
Once the packages are installed, the installer activates the systemd to start the Apache2 service and enables it to automatically start at system startup, every time the system is rebooted.
You can check the status of the service with the following command to ensure that it is up and running.
# systemctl status apache2
On Debian 10, the pgAdmin 4 WSGI application is configured to work with Apache HTTP server by default using the /etc/apache2/conf-available/pgadmin4.conf configuration file.
Before you can access the pgadmin4 web interface, if you have the UFW firewall running (it is usually disabled by default), you need to open port 80 (HTTP) to allow incoming traffic on Apache service as follows.
# ufw allow 80 # ufw allow 443 # ufw status
Accessing the pgAdmin 4 Web Interface
Now you can access the pgAdmin 4 web interface. Open a web browser and point it to the following address and click Enter.
http://SERVER_IP/pgadmin4 OR http://localhost/pgadmin4
Once the pgAdmin 4 web login interface appears, enter the email address and password that you set earlier on to authenticate. Then click log in.
After a successful login, you will land at the pgAdmin4 web interface default dashboard. To connect to a database server, click on Add New Server.
Then add the new server connection name and a comment. And click on the Connection Tab to provide the connection details I.e hostname, database name, database username, and password as shown in the following screenshot. Once you are done, click Save.
Under the Browser tree, you should now have at least one server connection showing the connection name, number of databases, roles, and table space. Double click on the Database link to view the server performance overview under the Dashboard.

I have this message:
Unable to find the pgadmin4-apache2 package.
Any suggestions, please?
The problem occurs due to the missing repository for pgadmin in your local machine. To solve the issue, do the following below;
Please help me…
After the installation, I have lost the password for pgAdmin 4.
Tell me how to bypass registration on the page
I don’t think you can bypass the login feature. The only way is to use the password recovery feature which can only work if you have a working mail service.
Two days ago, we are unable to run pgAdmin4 on my 18.04.5 LTS server. I was presented with a “blank” page after login. We tried different browsers on different OS with the same issue. I posted the issue in the pgadmin-support list group, with the subject title “pgAdmin4 presents blank screen after login.”
One response from the community asked me to send in the pgAdmin4.log file by enabling the logging per instruction https://www.pgadmin.org/faq/#8.
But unfortunately, I could not locate where “config.py” was or where pgAdmin was installed. I’d highly appreciate it if you could provide some pointer to either this issue or where I may turn on the logging.
When I log in I keep landing on the Apache server welcome page, and not the pgadmin interface.
Try to delete the Apache server welcome page:
Hi there, I am trying to install pgAdmin4 on an 18.04 ubuntu server. When I tried to “apt install pgadmin4 pgadmin4-apache2” I ran into the following error:
I appreciate any suggestions.
Do the following.
Create /etc/apt/sources.list.d/pgdg.list file with this line in it:
Save the file and close it.
Then run these commands to install pgadmin4:
That did it! What do I need to do if any when a new release of pgAdmin4 is out?
The reason I am asking this question is that for about a year and a half, I have been using the containerized deployment. Since I never could get the volume-mapping working, each time when I want to upgrade, I lost my history, connections, settings, etc.
Thank you for sharing this great post and your support!
