pgadmin4 from apt.postgresql.org - ubuntu xenial

[Tony Bazeley]

Hi all, I've tried to install pgadmin4 from apt.postgresql.org and get the error below. I'm no python expert but both python-flask and python3-flask packages are installed. Would appreciate any thoughts on what I should try next Thanks Tony Bazeley tonbaz@muscat:~$ pgadmin4 Python path:  "" Python Home:  "" Webapp path:  "/usr/share/pgadmin4/web/pgAdmin4.py" Traceback (most recent call last):   File "/usr/share/pgadmin4/web/pgAdmin4.py", line 34, in <module>     import config   File "/usr/share/pgadmin4/web/config.py", line 30, in <module>     from pgadmin.utils import env, IS_PY2, IS_WIN, fs_short_path   File "/usr/share/pgadmin4/web/pgadmin/__init__.py", line 17, in <module>     from flask import Flask, abort, request, current_app, session, url_for ImportError: No module named 'flask'
