I can not find the url for your install.sh to use with wget
The download URL for the install.sh script is available on the Download page here:
I don't see it. I understand how to use install.sh but don't see that url (or any other for that matter)
I have only text terminal access to the machine in question.
on the page you pointed me to why not post the clear text:
at the moment it is only present as part of this sentence:
The Virtualmin GPL installation script is available for Linux and FreeBSD or for Solaris and OpenSolaris 10 and 11.
It would be clearer.
