Thread: Unable to run PGAdmin in Ubuntu 24

Hello,

I'm using PostgreSQL and PGAdmin on a Ubuntu server.  Both worked when the server was on Ubuntu version 22, but after it was upgraded to 24, PGAdmin started causing an internal server error.  The Apache error log shows this:

[Mon Sep 16 11:24:55.627995 2024] [wsgi:error] [pid 163422] [remote 127.0.0.1:37332] mod_wsgi (pid=163422): Failed to exec Python script file '/usr/pgadmin4/web/pgAdmin4.wsgi'.

I've never seen this sort of error before, so any advice would be appreciated.

I just tried this command:

sudo apt reinstall pgadmin4

It gave me this error:

Reinstallation of pgadmin4 is not possible, it cannot be downloaded.

Hi Steven,

What is your pgAdmin version? You'll have to uninstall and install pgAdmin again.
