我发现很多人都遇到了同样的问题（包括我），所以我研究了解决方案并决定使用通过docker的pgadmin4来解决这个问题。我建议您现在使用带有docker的pgadmin4。在终端中按照以下步骤操作：

--install the docker on Ubuntu focal
$ sudo apt install docker.io

--Download the image
$ sudo docker pull dpage/pgadmin4

--Run the image
$ sudo docker run -p 80:80 --name=pgadmin -e "[email protected]" -e "PGADMIN_DEFAULT_PASSWORD=your_password" -d dpage/pgadmin4

--See the container status
$ sudo docker ps -a

打开网络浏览器并使用：http://本地主机

第一次您必须填写 PGADMIN_DEFAULT_EMAIL 中定义的电子邮件和 PGADMIN_DEFAULT_PASSWORD 中定义的密码。

其他时候，将显示 pgAdmin4 仪表板屏幕，您无需再次输入电子邮件和密码。

享受 ！
