Hello @myr ,
We have an approval mechanism for patches. There is a toggle button “Approve Automatically” located on top right corner under Operating System Patches. You can choose whether to enable or disable auto approval.
If you disable auto approval, it means you need to approve each new patch before it can be installed on any endpoint.
In your case, could you please check whether if this specific patch is “Approved”? You can check this from Patch Management → Operating System section and filter by “Title”. If the patch is not in “Approved” status, then you can not install the patch.
