I'm using a package from the OBS project devel:languages:python (python3-vdirsyncer if you need to know) on an openSUSE Leap 42.3 system and have therefore added https://download.opensuse.org/reposi...SUSE_Leap_42.3 to the list of configured repositories.
For several days now, whenever I try to install anything through YaST2, I get notified that this repository is not available.
Indeed, when I try to navigate to that URL I find that https://download.opensuse.org/reposi...guages:/python has only four subdirectories left:
openSUSE_Factory_ARM, openSUSE_Factory_PowerPC, openSUSE_Factory_zSystem, and openSUSE_Tumbleweed.
All the folders referring to openSUSE Leap or SLE are gone.

The OBS project still exists and still has the package I want.
But on https://build.opensuse.org/repositor...nguages:python I notice that the Publish Flag is set to disabled for openSUSE_Leap_42.3, openSUSE_Leap_15.0, SLE_15, and SLE_12_SP4, which I imagine is the reason for my woes.

How did that come and what can I do to have it re-enabled?
