I followed the given steps in https://helm.workshop.flagger.dev/prerequisites/#flux.
But it failed at helmv3 upgrade step.

helmv3 upgrade -i helm-operator fluxcd/helm-operator --wait \
--namespace fluxcd \
--set git.ssh.secretName=flux-git-deploy \
--set git.pollInterval=1m \
--set chartsSyncInterval=1m \

--set image.repository=docker.io/fluxcd/helm-operator-prerelease \

zsh: no matches found: configureRepositories.repositories[0].name=stable

Explain that Flux 2 is coming up and this workshop is not transitioned yet.

While following the workshop steps, I couldn't get the nginx-ingress to work properly.

Checked the version they are working with, and I am not seeing the 1.19.0 version any more.

Solved it myself with upgrading to version 1.25.0
