Sitecore install error "The virtual machine could not be started because a required feature is not installed" - sitecore

I think this will only be relevant to people who have also tried installing Sitecore so I’m not going to write every step of the process. 

After running the ./up.ps1 command, I get this error message shown in the image
sitecore error message
The 2nd error can’t be correct because I am logged into docker so it could only be the first error of “The virtual machine could not be started because a required feature is not installed”

Any ideas as to what’s causing this error?
I was following the instructions given by sitecore and was expecting their sitecore environment to start running

Can't access Elastic Beanstalk Configuration: A problem occurred while loading your page: Configuration validation exception: Invalid option value

My application is running on Elastic beanstalk AL2 with docker. It is still up and running, this issue is not user facing and only internal to AWS.
I upgraded to AL2 about 7 months ago and there were no problems. Recently I logged into to Elastic Beanstalk console to look into upgrading the platform. When I clicked on "Configuration" I get an error and redirected back to the applications list.
The error says:
Error

A problem occurred while loading your page: Configuration validation exception: Invalid option value: 'awseb-e-XXXXXXXX-stack-AWSEBSecurityGroup-XXXXXXXX’ (Namespace: 'aws:autoscaling:launchconfiguration', OptionName: 'SecurityGroups'): The security group 'awseb-e-XXXXXXXX-stack-AWSEBSecurityGroup-XXXXXXXX' does not exist
The error before this actually referenced a launch template so when I created a version 2 of the launch template but without the errored security group (as indicated by the UI) then this error message changed to the one we see above.
I tried redeploying thinking new setting need to take effect. Didn't work. Error still present.
I tried creating a new unrelated environment from scratch, but it has the same error message when clicking on Configuration.
I tried cloning production environment but am blocked with the same error message.
I also posted this question here: https://repost.aws/questions/QU4VTSJDyCT7OtIIgPCblUPA/elastic-beanstalk-unable-to-access-environments-configuration-error-a-problem-occurred-while-loading-your-page-configuration-validation-exception
I tried the suggestions but neither worked.
Any ideas on how to fix or debug this further?
Thank you

Coldfusion Builder check for updates not working

Running CF builder 3, Help > Check for Updates throws an error -- "Unable to read repository at http://ahtik.com/eclipse-update/content.xml.
peer not authenticated". Not sure why it's looking there, but I pasted the url in browser and indeed got a 404 error. Is there a way to change where CFB looks for this update check?
Okay, I was getting the "No repository found at file:/Y:/.." message because the path was listed under window > preferences > Install/Update > Available Software Sites. Y was a network drive that we disabled, but beyond that, it looks like my CFB was incorrectly configured for updates anyway. I spent some time trying to add in the standalone patch at the top of https://helpx.adobe.com/coldfusion/kb/coldfusion-builder-3-updates.html, but kept getting error messages. I inherited this copy of CFB a year ago, so I just did a clean reinstall. After that did Help > Check for Updates, it found and installed an update, restarted CFB, and now everything's good.

ColdFusion 2016 - Security service not available

CF 2016 on windows10 with IIS
I've checked other threads on similar issues and they don't appear to apply.
My laptop has needed to be crash-started on a number of occasions recently due to the laptop not waking up from sleep mode. A couple of times ColdFusion 2016 didn't start automatically and needed to be manually started. Now, ColdFusion appears to be starting automatically, but now I'm getting an error:
HTTP Error 500.0 - The Security service is not available.
I'm afraid I have no idea where to start on this or even what additional information to provide. So, I would really appreciate any hints.
The remainder of the error has the following information:
Detailed Error Information:
Module: IsapiModule Notification: ExecuteRequestHandler
Handler: ISAPI-dll
Error Code: 0x00000000
Requested URL: http://zbay_sys:80/jakarta/isapi_redirect.dll
Physical Path : C:\ColdFusion2016\config\wsconfig\1\isapi_redirect.dll
Logon Method: Anonymous
Logon User : Anonymous
I really hope I don't have to re-install CF
Glad, that you are sorted.
The error message says, "The Security service is not available." Thus IIS is showing http based error 500. If the service is not starting, there could likely be a problem at ColdFusion end.
Please try the following, if you face the similar issue in future:–
Stop ColdFusion service (if not already)
Launch Command prompt as Administrator
Browse to cf_root\cfusion\bin and run the following
command coldfusion.exe -start console
Try to access the CF Admin, once the services are started.
In case it gives an error message, please share the same.

NATS Error while developing echo service

I'm trying to develop a system service, so I use the echo service as a test.
I developed the service by following the directions on the CF doc.
Now the echo node can be running, but the echo gateway failed with the error "echo_gateway - pid=15040 tid=9321 fid=290e ERROR -- Exiting due to NATS error: Could not connect to server on nats://localhost:4222/"
I got into this issue and struck for almost a week finally someone helped me to resolve it. The underlying problemn is something else and since errors are not trapped properly it gives a wrong message. You need to goto github and get the latest code base. The fix for this issue is http://reviews.cloudfoundry.org/#/c/8891 . Once you fix this issue, you will most likely encounter a timeout field issue. the solution for that is to define the timeout field gateway.yml
A few additional properties became required in the echo_gateway.yml.erb file - specifically, the latest were default_plan and timeout, under the service group. The properties have been added to the appropriate file in the vcap-services-sample-release repo.
Looks like the fix for the misleading error has been merged into github. I haven't updated and verified this myself just yet but the gerrit comments indicate the solution is the same as what the node base has had for some time. I did previously run into that error handling and it was far more helpful.

Errors at Embedded Cassandra server startup

I am trying to use EmbeddedCassandraService to instantiate a Cassandra server in my unit tests. But I am getting this error. Any idea what can be causing this?
ERROR org.apache.cassandra.config.DatabaseDescriptor - Fatal error:
null; Can't construct a java object for
tag:yaml.org,2002:org.apache.cassandra.config.Config; exception=No
single argument constructor found for class
org.apache.cassandra.config.Config Bad configuration; unable to start
server
I used a configuration which is working in a standalone installation.
This thread and bug report from the Cassandra users mailing list may help, as it reports the same error message - what version of Cassandra are you using? (The bug report is against 0.7 beta 2)
