Thanks,

so I have googled further and found a number of alternatives:
- TightVNC
- X11VNC
- TigerVNC
(and there might be more...)

So now I would like to know if a package like tightvnc is *available* via apt,
but without installing it.

Is there a command to check the availability of a package in the apt repository
without actually installing it?

I am confused by the behaviour of apt install, because sometimes it works to
check things and then asks if I want to continue with the install.
But other times it just performs the installation directly, which is not really
optimal (the confusion, I mean).

So is there another way to know if a package is actually present on the apt
repo?

Googling just gives me responses on how to check what apt has *already*
installed on my system...

Btw, who is maintaining TigerVNC? Is it the RealVNC company or someone else?
