Windows server 2019 - Cannot install features

Usman Siddiqui1 6

I am getting below error while trying to add either WAS-NET-Environment or NET-HTTP-Activation features in windows server 2019. I have to install these features using powershell since I have to do it on number of servers? Any ideas?

Add-WindowsFeature : The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed. Error: 0x800f0954
At line:1 char:1

I mean to say that this server is configured to connect to a WSUS server to get updates. Server itself is not running WSUS role. My objective is to install .Net Framework feature on it without bypassing wsus server which is the workaround suggested in the link LimitlessTechnology-2700 shared.

The error was:

Error: 0x800f0954 At line:1 char:63 + ... C:\Users\myaccount\Documents\installed.xml" | Install-WindowsFeature + ~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (@{Vhd=; Credent...Name=localhost}:PSObject) [Install-WindowsFeature], Exception + FullyQualifiedErrorId : DISMAPI_Error__Failed_To_Enable_Updates,Microsoft.Windows.ServerManager.Commands.AddWind owsFeatureCommand

So my problem was with microsoft updates

In my environment i solved in this way:

(see https://woshub.com/pswindowsupdate-module/)

I installed Module PSWindowsUpdate and then updated os
Install-Module -Name PSWindowsUpdate -Force

Get-Package -Name PSWindowsUpdate

Add-WUServiceManager -ServiceID "7971f918-a847-4430-9279-4a52d1efe18d" -AddServiceFlag 7 #default to "microsoft update"

Get-WUlist -MicrosoftUpdate

Install-WindowsUpdate -MicrosoftUpdate -AcceptAll -AutoReboot

Installed the features from an .xml of features exported from another server

Import-Clixml "C:\Users\myaccount\Documents\installed.xml" | Install-WindowsFeature

I hope this help
