Ubuntu 22.04 upgrade problems

I have just upgraded a laptop from Ubuntu 18.04 -> 20.04 -> 22.04 and am
having problems getting pgAmin4 installed. I followed the steps at
https://www.pgadmin.org/download/pgadmin-4-apt/ adding the repo and then
'apt update', 'apt install pgadmin4' but my /usr/pgadmin4/bin/ directory
contains only 'setup-web.sh' and nothing else. 'apt search' lists pgadmin4
as being installed. I've done 'apt remove' and 'apt install' trying to
install just pgadmin4 and pgadmin4-destop.

I did do 'apt remove pgadmin4' before trying to install the first time
around, but I did not delete any pgadmin4 files or directories in my home
directory that were from the Ubuntu 18.04 installation.

I realize that my problems may be more in the apt realm than the pgadmin
realm but I figured I start by seeking advice here first.
