Dunno, it can’t be completely on KDE’s end, if at all, because I just tried a Manjaro install with KDE and it’s adding them fine
Yes Manjaro works fine, maybe the dev’s fixed what ever the problem was ???
Manjaro is very far removed from Arch unlike Antergos which only adds a repo and some Antergos specific packages (all UI stuff), otherwise it’s the same as Arch. I installed Arch and same issue there, as I said before it’s a KDE issue. I’ll stick to Arch since this project has ended although I really love this distro.
For existing Antergos users: there is no need to worry about your installed systems as they will continue to receive updates directly from Arch. Soon, we will release an update that will remove the Antergos repos from your system along with any Antergos-specific packages that no longer serve a purpose due to the project ending. Once that is completed, any packages installed from the Antergos repo that are in the AUR will begin to receive updates from there.
