Root Cause Classification: Infrastructure (external dependency outage)

Failure Details (from logs):

##[group]Installing v3.9.2 Downloading 'v3.9.2' from 'https://get.helm.sh' Waiting 16 seconds before trying again Waiting 19 seconds before trying again ##[error]Error: Failed to download Helm from location https://get.helm.sh/helm-v3.9.2-linux-amd64.tar.gz 

Analysis:

• The lint job failed during the "Install helm" step using azure/setup-helm@v4.3.1
• This indicates an availability or connectivity issue with get.helm.sh, not a code/test problem
• All other jobs (tests, build, e2e) succeeded; the required check failed only due to lint depending on Helm
• Timing aligns with the Slack alert; the failure occurred minutes before the notification

Duplicates Search (none found):

• repo:coder/internal "Failed to download Helm"
• repo:coder/internal get.helm.sh
• repo:coder/internal "azure/setup-helm" OR "Install helm"
• Checked last 30 days of closed issues for similar infra outages

Context / Ownership:

• CI workflow file: .github/workflows/ci.yaml (lint job uses azure/setup-helm v3.9.2)
• A follow-up fix landed to work around the outage: "ci: workaround for get.helm.sh outage" — coder/coder@50749d1 (2025-10-29 17:33Z)

Proposed Actions:

• Monitor for recurrence; if get.helm.sh remains flaky, consider switching to an alternate installation method (e.g., apt repository or mirrored tarball) permanently for CI
• Ensure the workaround in 50749d1 is backported or retained as needed

Assignment:

• Leaving unassigned as this is CI infrastructure. Tagging CI/DevEx area for visibility.
