In Update Manager, update stands for all patches, extensions, and upgrades that you can apply with Update Manager. The compliance state of the updates in baselines and baseline groups that you attach to objects in your inventory is calculated after you perform a scan of the target object.

Conflict
The update conflicts with either an existing update on the host or another update in the Update Manager patch repository. Update Manager reports the type of conflict. A conflict does not indicate any problem on the target object. It just means that the current baseline selection is in conflict. You can perform scan, remediation, and staging operations. In most cases, you can take action to resolve the conflict.
Conflicting New Module
The host update is a new module that provides software for the first time, but is in conflict with either an existing update on the host or another update in the Update Manager repository. Update Manager reports the type of conflict. A conflict does not indicate any problem on the target object. It just means that the current baseline selection is in conflict. You can perform scan, remediation, and staging operations. In most cases, you must take action to resolve the conflict.
Incompatible Hardware
The hardware of the selected object is incompatible or has insufficient resources to support the update. For example, when you perform a host upgrade scan against a 32-bit host or if a host has insufficient RAM.
Installed
Installed compliance state indicates that the update is installed on the target object, and no further user action is required.
Missing
Missing compliance state indicates that the update is applicable to the target object, but not yet installed. You must perform a remediation on the target object with this update, so that the update becomes compliant.
Missing Package
This state occurs when metadata for the update is in the depot but the corresponding binary payload is missing. The reasons can be that the product might not have an update for a given locale; the Update Manager patch repository is deleted or corrupt, and Update Manager no longer has Internet access to download updates; or you have manually deleted an upgrade package from the Update Manager repository.
New Module
New module compliance state indicates that the update is a new module. An update in this compliance state cannot be installed when it is part of a host patch baseline. When it is part of a host extension baseline, the new module state signifies that the module is missing on the host and can be provisioned by remediation. The compliance state of the baseline depends on the type of baseline containing the update in new module state. If the baseline is a host patch baseline, the overall status of the baseline is compliant. If the baseline is a host extension baseline, the overall status of the baseline is not compliant.
Not Applicable
Not applicable compliance state indicates that the patch is not applicable to the target object. A patch might be in not applicable compliance state for one of the following reasons:
  • There are other patches in the Update Manager patch repository that obsolete this patch.
  • The update does not apply to the target object.
Not Installable
The update cannot be installed. The scan operation might succeed on the target object, but remediation cannot be performed.
Obsoleted By Host
This compliance state applies mainly to patches. The target object has a newer version of the patch. For example, if a patch has multiple versions, after you apply the latest version to the host, the earlier versions of the patch are in Obsoleted By Host compliance state.
Staged
This compliance state applies to host patches and host extensions. It indicates that the update is copied from the Update Manager repository to the host, but is not yet installed. Staged compliance state might occur only when you scan hosts running ESXi 6.0 and later.
Unknown
A patch is in unknown state for a target object until Update Manager successfully scans the object. A scan might not succeed if the target object is of an unsupported version, if Update Manager lacks metadata, or if the patch metadata is corrupt.
Unsupported Upgrade
The upgrade path is not possible. For example, the current hardware version of the virtual machine is greater than the highest version supported on the host.
