UPGRADE FAILED: another operation (install/upgrade/rollback) is in progress

Question

Yesterday I stopped a helm upgrade when it was running on a release pipeline in Azure DevOps and the followings deployments got it failure.

I tried to see the chart that has failed with the aim of delete it but the chart of the microservice ("auth") doesn't appear. I used the command «helm list -n [namespace_of_AKS]» and it doesn't appear.

What can i do to solve this problem?

Helm List

Answer 1

helm ls -a -n {namespace} will list all releases within a namespace, regardless of status.

You can also use helm ls -aA instead to list all releases in all namespaces -- in case you actually deployed the release to a different namespace (I've done that before)

Answer 2

This error can happen for few reasons, but it most commonly occurs when there is an interruption during the upgrade/install process as you already mentioned.

To fix this one may need to, first rollback to another version, then reinstall or helm upgrade again.

Try below command to list

helm ls --namespace <namespace>

but you may note that when running that command ,it may not show any columns with information

Try to check the history of the previous deployment

helm history <release> --namespace <namespace>

This provides with information mostly like the original installation was never completed successfully and is pending state something like STATUS: pending-upgrade state.

To escape from this state, use the rollback command:

helm rollback <release> <revision> --namespace <namespace>

revision is optional, but you should try to provide it.

You may then try to issue your original command again to upgrade or reinstall.
