libreadline6-dev is not a valid Ubuntu 16.10 package

[danielpclark]

I'm running Ubuntu 16.10 and every time I install a new Ruby version RVM asks me for my sudo password because of libreadline6-dev. The problem is that there is no package for by that name for my distro. See the output here:

apt list libreadline*

As one who is very security minded this really annoys me as a security risk to be asked for a sudo password mid script. Also since RVM fails to get the package it's asking to install it's going to ask for the same thing every time. I have libreadline-dev and everything works fine with it.

Please update the dependency from libreadline6-dev to libreadline-dev and please don't ever ask me for a sudo password during install. Tell me what I need to install and quit, I'll do it by hand and then run the install again. I can change paths, permissions, and dependencies all on my own without handing over my systems security to an install script.
