Why is there an error when installing PgAdmin4?

Question

linux

Hello. Installed PostgreSQL on Ubuntu 20.04.2 LTS. But when I try to install the PgAdmin4 graphical utility, I get an error: No installation candidate was found for the package "pgadmin4". What does it mean?

Answer 1

I solved the problem myself. Had to add the line "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" to the pgdg.list file in /etc/apt/sources.list.d

Answer 2

who will connect the repository?
this package is not in their ubuntu repositories

sudo apt-get -y install apt-transport-https lsb-release ca-certificates curl
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/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list'
sudo apt-get update

and only after that you can install

Answer 3

Means that you have not connected the repository with this package
