A while back, https://github.com/salfter/portage was added to the layman registry. I'm moving all of my repos from GitHub to GitLab, so the URL needs to be updated to point to https://gitlab.com/salfter/portage.git.
Updated. May take a few minutes to propagate.
Took a look at https://api.gentoo.org/overlays/repositories.xml after an update failed today...found this URL: https://gitlab.com/salfter/portage It's missing the ".git" on the end. Unlike GitHub, this is important for GitLab. Fetching the repo with layman currently fails. It needs to be changed to the following: https://gitlab.com/salfter/portage.git
I'm sorry for this. Fixed now.
Works like a champ now...thanks!
