While running the latest kernelcare update from 2.32 to 2.34 on our Ubuntu 18.04 boxes the update fails because it cannot find a libcare.socket service and cannot start it.
A subsequent update of the kernelcare package will enable and start this service, but apt still shows warnings.
It seems there might be some order issue in the postinst of the .deb package
A subsequent update of the kernelcare package will enable and start this service, but apt still shows warnings.
