.NET core 2.0, errors installing on linux

.NET Core 2.0 is finally out, and I immediately try to install it on every machine and especially in my linux test machines. In one of my Ubuntu machine I got an installation problem, a generic error of apt-get and I was a little bit puzzled on why the installation fail.

Since in windows the most common cause of .NET Core installation error is the presence of an old package (especially the preview version), I decide to uninstall all previous installation of .NET core on that machine. Luckly enough, doing this on linux is really simple, first of all I list all installed packages that have dotnet in the name

sudo apt list --installed | grep dotnet

This is what I got after a clean installation of .NET core 2.0

But in that specific virtual machine I got several versions and a preview of 2.0, so I decided to uninstall every pacakge using the command sudo apt-get purge packagename, finally, after all packages were uninstalled I issued a sudo apt-get clean and finally I tried to install again .NET core 2.0 and everything went good.

If you have any installation problem of .net core under linux, just uninstall everything related with dotnet core with apt-get purge and this should fix your problems.
