Our automated repository checks [1] have detected that the 'arcon' repository lacks masters= specification. This causes some Package Managers to be unable to use the repository, and will become fatal in Portage at some point. Master repositories provide various resources to the sub-repositories in the way of inheritance. For example, a repository inherits eclasses, licenses, mirrors provided by the master. Additionally, it requires the master repository to be enabled, therefore allowing the packages provided by it to satisfy dependencies. In particular, if your repository uses any eclasses, licenses, mirrors, global USE flags or any other resources provided by the Gentoo repository, or depends on any packages provided by it, it needs to specify in metadata/layout.conf: masters = gentoo However, if your repository is fully stand-alone and any package provided by it can be installed without any other repository being enabled, you should specify empty masters= to indicate this: masters = Please fix the issue ASAP. It prevents our tools from working on the repository, and mirroring it. We reserve the right to remove it if we do not receive any reply within 2 weeks.

Seeing no reply, I'm removing the repository from the official list. If it's a Gentoo-hosted git repository, the actual git repository will still be live -- it just won't be listed by layman. If you fix the mentioned QA issue, please reopen the bug and I'll readd the repository shortly.
