Thanks for pointing me to this command!
I tested it on my upgraded laptop which is running now Ubuntu Mate 20.04 LTS:

$ apt policy tigervnc-standalone-server
tigervnc-standalone-server:
  Installed: (none)
  Candidate: 1.10.1+dfsg-3
  Version table:
     1.10.1+dfsg-3 500
        500 http://se.archive.ubuntu.com/ubuntu focal/universe amd64 Packages

$ apt policy x11vnc
x11vnc:
  Installed: (none)
  Candidate: 0.9.16-3
  Version table:
     0.9.16-3 500
        500 http://se.archive.ubuntu.com/ubuntu focal/universe amd64 Packages

$ apt policy tightvncserver
tightvncserver:
  Installed: (none)
  Candidate: 1.3.10-0ubuntu5
  Version table:
     1.3.10-0ubuntu5 500
        500 http://se.archive.ubuntu.com/ubuntu focal/universe amd64 Packages

$ apt policy vnc4server
vnc4server:
  Installed: (none)
  Candidate: (none)
  Version table:

So the vnc4server I had installed before the dist-upgrade is the only one not
available...

But the vnc4server config files are still present so should I find and remove
them before installing TigerVNC?

According to my notes I edited these 2 files when in stalling vnc4server:

$HOME/.vnc/xstartup
/etc/systemd/system/vncserver at .service
