The Cache Goes Stale
When you add a repo, Helm caches its index once. New chart versions published later are invisible until you refresh that local copy.
The Refresh Command
helm repo update re-downloads the index for every repo you have added, syncing your local view with what each server now offers.
helm repo updateWhat It Touches
Update only refreshes index files. It does not install, upgrade, or change anything running on your cluster. It is completely safe to run anytime.
Reading the Output
Helm prints a line per repo as it fetches, ending with a cheerful done message. A failed line means that repo URL was unreachable.

Update Complete.Update One Repo
Have many repos but only care about one? Pass its name to refresh just that single repo and skip the rest.
helm repo update bitnamiWhen to Run It
Run update right before you search or install if you want the newest versions, or whenever a chart you expect does not appear yet.
Add Already Updates
A fresh helm repo add fetches the index right away. You only need update for repos that were added earlier and may have moved on since.
A Habit in Automation
In CI scripts it is common to add repos then immediately run helm repo update, guaranteeing the pipeline sees the latest published charts.

helm repo updateStale Means Old Versions
Skip the refresh and your searches show only what existed when you last synced. You might install an outdated chart without realizing it.
Cheap and Fast
Index files are small, so updating is quick and low-cost. There is no harm in running helm repo update often to stay current.
Local, Not Cluster
Remember the update lives entirely on your machine. Your teammates and CI runners each refresh their own local index independently.
Quick Check
You added a repo last week and a new chart version just shipped. What gets it to show up?
Recap
