n 8.1 … “Working with Helm and Charts”. I run the following :

I am currently in LAB 8.1 "Working With Helm and Charts"

I am using the latest version of helm : Helm v4.1.4
The lesson uses : Helm v3.19.0

Commands in the LAB:

helm repo add ealenn https://ealenn.github.io/charts

then

helm repo update

and …

helm upgrade -i tester ealenn/echo-server --debug

However, echo-server’s .tgz file is nowhere to be found in :

CHART PATH: /home/student/.cache/helm/repository/

They mention that the .tgz might be under a different name. However. there is no .tgz file present after running the command.

Are the instructions wrong?

    Hi @toddrickson,

    I am using the latest version of helm : Helm v4.1.4

    This decision is causing the inconsistencies you are experiencing. Helm v4 introduced significant changes from v3, that includes helm's local cache filesystem and how charts are stored and used. The output snippets provided for validation are consistent with the software version suggested in the lab instructions. Deviating from the instructions provided in the lab guide typically lead to such inconsistencies.

    Question:

    What is the linux command to uninstall Helm v4.1.4 ?

    I tried :

    student@cp:~$ helm version
    version.BuildInfo{Version:"v4.1.4", GitCommit:"05fa37973dc9e42b76e1d2883494c87174b6074f", GitTreeState:"clean", GoVersion:"go1.25.9", KubeClientVersion:"v1.35"}
    student@cp:~$ helm list --all-namespaces
    NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
    student@cp:~$ helm uninstall v4.1.4
    Error: uninstall: Release not loaded: v4.1.4: release: not found
    student@cp:~$ helm uninstall go1.25.9
    Error: uninstall: Release not loaded: go1.25.9: release: not found
    student@cp:~$ helm uninstall v1.35
    Error: uninstall: Release not loaded: v1.35: release: not found

    Hi @toddrickson,

    The helm uninstall ... command only removes an application release from the cluster, it does not remove itself.

    The linux command to uninstall a utility from a linux host depends on the linux distribution - essentially it is the package manager, but it removes packages it installed in the first place.

    However, you can revisit Step 3 and remove the helm binary, then Step 2 to remove the compressed archive and the expanded directory. If you installed helm by other means, then reverse those installation steps to remove the utility from the system.

    Regards,
