[Simone Pelosi]

Aligning with Launchpad's schedule, Mantic Translations opening

Adding mantic to releaseversions-ubuntu

[Sebastien Bacher (seb128)]

Thanks Simone. Should we disable kinetic from the cron job perhaps? It's neither the current stable nor the LTS (also maybe lunar since we don't do langpacks updated in no LTS cycle)

[Sebastien Bacher (seb128)]

We discussed it by chat, let's merge it and I will disable kinetic in a commit after

review: Approve

[Simone Pelosi (pelpsi)]

Thank you Sebastien!
