Hi Team,

I was trying to install Undercloud on Centos 8 using the link below, but facing error in executing "openstack undercloud install" command. The error is in prefetch image

Steps followed:

1. Created a non root stack user

sudo useradd stack
sudo passwd stack # specify a password
echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack
sudo chmod 0440 /etc/sudoers.d/stack
su - stack

2. Install the python-tripleo-repos

sudo dnf install -y https://trunk.rdoproject.org/centos8/component/tripleo/current/python3-tripleo-repos-0.1.1-0.20210915165829.6d878bb.el8.noarch.rpm
In order to install victoria release, executed the command - sudo -E tripleo-repos -b victoria current ceph

3. As per the document, "The remaining repositories configuration steps below should not be done for stable releases!"

So, I didn't executed the command - "sudo -E tripleo-repos current-tripleo-dev ceph"
Is my understanding correct? This step has to be skipped in case we are going with a stable victoria release?

4. Modified undercloud.conf file and executed the command

openstack undercloud install

ISSUE:

5. In order to eliminate the problem, I manually installed the image -

sudo podman pull quay.io/tripleovictoria/openstack-swift-account:current-tripleo

After re-executing, then it again failed for the keystone image, which was already installed on the system. I verified in sudo podman images command

I tried running this 5-6 times and issue generates randomly for any openstack image ( sometimes for rabbitmq sometimes for swift, keystone) which is already installed in machine

Can someone please help or suggest what step I am missing

Note: This I have tried using Centos 8 Stream and Centos 8.4(using --no-stream), but same issue is observed in both
