Answer 1

The process involves two steps:

1. Download the needed files from here or any other location.

2. Then make file executable with:

   chmod +x VNC-Viewer-6.0.2-Linux-x64
   

3. Then move it to say your home directory and run it from there, or any other location:

   mv VNC-Viewer-6.0.2-Linux-x64 ~/
   
   ./VNC-Viewer-6.0.2-Linux-x64
   

Note: You don't install you just run it.

Answer 2

There are many VNC clients. Some have the same vncviewer executable. One is TigerVNC which is available in the package manager:

sudo apt install tigervnc-viewer
vncviewer <ip>:<display/port>
