How to install PgAdmin4 on Ubuntu 18.04 Server mode

Question

I am using an ubuntu 18.04 server through putty on windows 10. I am trying to install PgAdmin4 on it.

I am using this tutorial for that: How to install PgAdmin4 on Ubuntu 18.04 Server mode

When I reach the step Configure PgAdmin4 using config_local.py and run the command:

vim ~/.pgadmin4/lib/python2.7/site-packages/pgadmin4/config_local.py

The terminal shows few blue dots on left side of the screen vertically, each line having one of left side corner and at the bottom right of screen it writes 1,1 All and terminal is halted. Nothing happens.

I am not able to understand what to do. I am a novice to ubuntu.

When you type

vim ~/.pgadmin4/lib/python2.7/site-packages/pgadmin4/config_local.py

You said The terminal shows few blue dots on left side of the screen vertically, each line having one of left side corner and at the bottom right of screen it writes 1,1 All and terminal is halted.

I think this fine, at the bottom right of screen writes 1,1 ALL mean your cursor at 1 line 1 column on all text file.

When you try to save file, it raises error: "~/.pgadmin4/lib/python2.7/site-packages/pgadmin4/config_local.py" E212: Can't open file for writing. for save file using VIM try with type :w <filename> and exit with :quit.

After it's written and saved. execute your python file with sudo python config_local.py. see below.

And then when you run pgAdmin4.py the command, it raises error python: can't open file '/root/.pgadmin4/lib/python2.7/site-packages/pgadmin4/pgAdmin4.py': [Error 2] No such file or directory. you get it error cause you doesn't know where pgAdmin4 data stored. check it with locate pgadmin4 and you can found it at /usr/local/bin/.. path. after that you can execute pgAdmin4.py see below.

If the output can showed like on your link. Congrats Sir, you can try the next steps on your link.

Hope this helps Sir.
