VMware vRealize Auotmation 8.0 Deployment Failed - Known Issue

When i was installing vRA 8 in my Test Environment, it was failing again and again. I have tried couple of time but it was failing at same stage then i searched VMware Documentation and Found it is One of Known Issue. Lets see how to fix it:-

1. My installation was getting Failed. Then i logged in to vRealize Lifecycle Manage and have seen this error message

2. I have checked VMware Documentation and find this KB https://kb.vmware.com/s/article/76870?lang=en_US&queryTerm=76870. I followed this KB Step by Step :-

(A) Login to vRA through SSH Client (Example Putty)
kubectl -n prelude get pods

The status of the vco-app pod is CrashLoopBackOff

(B)   Confirm the error by running the following command on the appliance:

kubectl -n prelude logs vco-app-<ID from previous command> -c install-rpms

You are required to change your password immediately (password expired)
groupadd: PAM: Authentication token is no longer valid; new one required

(C) Take the backup of deployment.yaml file by following steps given below

(D) Edit deployment.yaml file. I have used VI editor

vi deployment.yaml

Press "I"

edit the line /init_run.sh = add this "sed -i 's/root:.*/root:x:18135:0:99999:7:::/g' /etc/shadow && sed -i 's/vco:.*/vco:x:18135:0:99999:7:::/g' /etc/shadow &&

"sed -i 's/root:.*/root:x:18135:0:99999:7:::/g' /etc/shadow && sed -i 's/vco:.*/vco:x:18135:0:99999:7:::/g' /etc/shadow && /init_run.sh"
