I encountered the same problem after upgrading from Ubuntu 20.04 to 22.04. Laurenz Albe's answer to simply reinstall PGAdmin 4 resolved the issue in my case. A downgrade from Python 3.10 to Python 3.9 was not necessary.

I have handle the error to switch pyhton3.10 to python3.9 and error fixed.

Just track the steps:

Install python3.9

Switch 3.10 to 3.9

You can use the link to do these steps.

https://www.how2shout.com/linux/install-python-3-9-or-3-8-on-ubuntu-22-04-lts-jammy-jellyfish/

or you just should reinstall pgAdmin4.

In my case after upgrading from Ubuntu 20.04 to 22.04, I found that the symbolic link to python whas broken.

To fix that I removed the link and create a new one to the correct path.

sudo ln -s /path/to/python3.8 /usr/pgadmin4/venv/bin/python3

To know where is python3.8 you can do which python3.8, or posibly simply which python

I faced the same trouble after updating Ubuntu from 22.10 to 23.04.

My winner set of steps was:

  • remove pgadmin.
  • go to pgadmin's web site and setup the repository for my new Ubuntu.
# Install the public key for the repository (if not done previously):
curl -fsS https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo gpg --dearmor -o /usr/share/keyrings/packages-pgadmin-org.gpg

# Create the repository configuration file:
sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/packages-pgadmin-org.gpg] https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'
  • Install pgadmin

sudo apt install pgadmin4

  • Happened to me too when upgrading from 22.10 to 23.04. I only needed to do `sudo apt remove pgadmin4-desktop pgadmin4-server` and then reinstall them back - that's it. I initially was worried it will remove the settings and stored DB connections, but everything stayed the same. There was also no need to install the public key, since I already had it from before. – Alexey Zagalsky Jun 21 '23 at 19:04

In my case i just needed to update the source of pgadmin4 to specific for my Ubuntu version in Software & Updates > Other Software from https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/impish/ to https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/jammy/
