Its worth mentioning that software-properties-gtk has a "Developer Options" tab that allows you to enabled and disabled -proposed (provided you aren't using a local mirror of the archive) and that is the preferred method to enable -proposed. Which wiki page were you looking at? It probably needs updating.
Additionally I briefly looked at the code for add-apt-repository and it seems to have support for enabling / disabling components (e.g. multiverse) but not pockets (e.g. -proposed). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829588 Title: make it easy to add proposed; help text outdated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1829588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
