These messages about ubuntu-jammy can be safely ignored, even if an operator has never uploaded or used ubuntu-jammy stemcells before.
In order to support uploading Jammy stemcells on Ops Manager 2.10, the runtime configs (including BOSH DNS) needed to be updated to also place jobs on any VMs deployed with the
ubuntu-
jammy
stemcell. This was done ahead of time to enable tile development teams to start testing with Jammy, and prep for when Jammy-based tiles are released later this year.
This allows operators to upload a Jammy stemcell (they are not publicly available on TanzuNet but OSS ones are listed on
bosh.io), but there are no tiles that support Jammy yet, so it would never be in use. The diff is strictly about runtime configs.
