Cache Not Found for Go 1.24 in GitHub Actions (actions/setup-go@v5) on Ubuntu 24

Bug Report: GitHub Actions Cache Not Found for Go 1.24 on Ubuntu 24

Description

The cache is not being restored for Go 1.24 when using actions/setup-go@v5 with caching enabled. The error message indicates that the cache key is not found.

Error Message

Warning: Cache not found for keys: setup-go-Linux-x64-ubuntu24-go-1.24.0-c7d09a7bd10e1d8e9f27bae09890ce6d036d31a3fe281a112bf305abd6dfe560

Action Version

actions/setup-go@v5

Platform

• Ubuntu 24
• macOS
• Windows

Runner Type

• GitHub-hosted
• Self-hosted

Tools Version

• Go version: 1.24

Repo Steps

1. Define the following step in a GitHub Actions workflow:

   - name: Setup Go
     uses: actions/setup-go@v5
     with:
       go-version: '1.24'
       cache-dependency-path: '**/go.sum'
   

2. Run the workflow on an Ubuntu 24 Self-hosted runner.
3. Observe the cache not being found and a warning appearing in the logs.

Expected Behaviour

• The workflow should successfully restore the cache for Go modules, improving job speed and avoiding redundant downloads.

Actual Behavior

• The cache is not found, and dependencies must be re-downloaded in every run, negating the benefit of caching.

The issue seems specific to the latest Go version (1.24).

Hello @mck-prakhar👋,
Thank you for reporting this issue. We will investigate it and get back to you as soon as we have some feedback.

I experienced the same behavior today (and did a search and found this GitHub issue). Then I realized 🙄 this is a cache, so of course nothing is cached the first time I run the workflow. When I ran the workflow a second time the cache was found. @mck-prakhar I'm not sure if this is the exact issue you had, however.

First time:

Warning: Cache not found for keys: setup-go-Linux-x64-ubuntu24-go-1.24.1-44360a77347d2a3ddcdc82941b93d1ce576ce33e0cba5d243d491dc881c9579a
Cache is not found

Second time:

Cache restored successfully
Cache restored from key: setup-go-Linux-x64-ubuntu24-go-1.24.1-44360a77347d2a3ddcdc82941b93d1ce576ce33e0cba5d243d491dc881c9579a

@priya-kinthali I think the confusing part is that this is a warning when it's expected behavior. Maybe it should not be a warning--maybe it should just be a log entry without the warning, like this:

Cache not found for keys: setup-go-Linux-x64-ubuntu24-go-1.24.1-44360a77347d2a3ddcdc82941b93d1ce576ce33e0cba5d243d491dc881c9579a
Cache is not found

For me its not working for any run, In every run I am getting the same warning. Could you please suggest me what runner type you are using is it github-hosted or self-hosted? Looking to understand the required config.

I have tried this with default go version supported by setup-go action i.e., 1.23.3, it is working fine but when I am specifying go version 1.24 explicitly its not working for me.
