I was use command

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'

E: The repository 'https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/n/a pgadmin4 Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

So I can't install pgadmin

Use Deepin linux 20.2.3

Answer 1

I am using Linux mint, issue has been fixed using the below command.

$ sudo curl https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo apt-key add
$ sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/focal pgadmin4 main" \
  > /etc/apt/sources.list.d/pgadmin4.list && apt update'
$ sudo apt update

And then, if you want desktop

$ sudo apt install pgadmin4-desktop

OR the web version:

$ sudo apt install pgadmin4-web 
$ sudo /usr/pgadmin4/bin/setup-web.sh

Answer 2

For Ubuntu 22.10 and other versions that complain about apt-key being deprecated, use this:

curl -fsS https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo gpg --dearmor -o /usr/share/keyrings/packages-pgadmin-org.gpg

sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/packages-pgadmin-org.gpg] https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/jammy pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'

Note that "jammy" is being used here in the ftp link. You may browse through the other versions and pick the one that matches your Ubuntu installation's version

sudo apt install pgadmin4

This installs both web and desktop versions.
