pgAdmin4 on Kubuntu Hirsute

Hi all,

I've just installed the latest Kubuntu (21.04 Hirsute) onto a new 
laptop, and I can't get pgAdmin4 5.2 to start. I know that Hirsute isn't 
supported (yet), but I'd appreciate a pointer or two if possible.

I added the apt repo for Groovy (as there's none for Hirsute) to my 
/etc/apt/sources.list.d, and did:

    sudo apt update
    sudo apt install pgadmin4-server

All seemed to go OK with the installation. On trying to start it, I get 
the "Waiting for pgAdmin 4 to start..." dialog, which eventually times 
out with "The pgAdmin4 server could not be contacted". The runtime 
environment info given in the error dialog is appended below.

I have the python-is-python3 package installed, which maps the "python" 
command to python3. The python version installed is 3.9.4. The 
pgadmin4-desktop and pgadmin4-server packages are installed

I could run pgAdmin from a docker image; but then (I presume?) I'd have 
to access it from a browser window... I will if I have to, but I'd 
prefer to use the self-contained application window.

Thanks in advance for any pointers.

Ray.
