Suggest using distro packages if known upstream ppas/repos exist
There are ubuntu and debian ppas maintained by @hvr afaik, which are recent and well maintained, so we could inform users of this possibility.
Due to a large amount of spam we do not allow new users to create repositories, they are "external" users. If you are a new user and want to create a repository, for example for forking GHC, open a new issue on ghc/ghc using the "get-verified" issue template
