Today Apertis is moving the APT repositories on https://repositories.apertis.org/ to dedicated Aptly instances to provide the ground for new features and streamlined maintenance.
As part of the transition older unmainained repositories will not be migrated.
Other than that, the transition should be completely transparent for users and does not require any change.
The full process will complete in a few days, with the OBS publisher being reworked to talk to the Aptly instances directly.
If you hit any issue, do not hesitate to reach out on this mailing list or on other channels.
Cheers, Emanuele on behalf of the Apertis Team
