As we continue our journey from Alpha releases and eventually to Beta, you can continue to download the latest releases from our GitHub repository .  However, our goal has always been to enable installation through popular existing Linux package management tools like apt-get and yum .I am pleased to announce that we have now published PowerShell Core 6.0 alpha.15 to https://packages.microsoft.com

After registering the Microsoft repository once as superuser, from then on, you just need to use either sudo apt-get install powershell or sudo yum update powershell (depending on which distro you are using) to update it. 

We plan to simultaneously publish to https://packages.microsoft.com and our GitHub repository for each new release.
