- Remove the default channel from MCRConfig.SetDefaults() — channel is now a required field. An absent or empty spec.mcr.channel produces a clear fatal error at parse time, consistent with how spec.mke.version is handled. - Add validation in ClusterSpec.UnmarshalYAML: if MCR channel is empty after unmarshal (mcr block absent or channel field omitted), return an actionable error directing the user to set e.g. channel: stable-29.4. - Set DEBIAN_FRONTEND=noninteractive on the apt-get update call in the Ubuntu MCR installer (InstallPackage from rig already sets it for install calls). - Add policy-rc.d comment documenting the deferred dpkg post-install concern. - Update all cluster_test.go fixtures to include mcr.channel: stable. - Add TestMissingMCRChannelFails and TestMCRConfig_ChannelRequired tests.

What
Require
spec.mcr.channelexplicitly in the launchpad config and fixDEBIAN_FRONTENDon the Ubuntu MCR apt-get update call.Why
Users following the MKE 3.8 doc template (which omits the
mcrblock) hit a silent default that caused MCR install failures. Makingmcr.channelrequired produces a clear parse-time error before any install begins, consistent with howspec.mke.versionis handled.How
