🔄 Build Failed: Git Checkout Error

fatal: Remote branch v0.20.4 not found in upstream origin

Build Details

Category	Details
Build System	git
Failure Point	git clone --quiet --origin=origin --config=user.name=Melange Build --config=user.email=melange-build@cgr.dev --config=advice.detachedHead=false --branch=v0.20.4 --depth=1 https://github.com/google/go-containerregistry /tmp/tmp.hrKlbG

Root Cause Analysis 🔍

The build is attempting to clone the go-containerregistry repository with branch 'v0.20.4', but v0.20.4 is likely a tag, not a branch. The git checkout command is incorrectly using --branch flag for what should be a tag checkout. In git, tags and branches are different references, and using the wrong flag causes this error.

Analysis

Analyzing the similar fixed build failures, I found a consistent pattern: all failures involve Git checkouts where tags are incorrectly treated as branches. This is evident in all three examples where build failures occurred when trying to use the --branch flag with version tags like 'v2.32.0', '0.4.0', and 'v1.1295.4'. The fixes all addressed this same core issue but in slightly different ways:

1. Example #0 (filebrowser.yaml): Added missing dependencies and bumped the epoch.
2. Example Add binutils-2.39 configuration #1 (py3-typing-inspection.yaml): Created a new package file with correct tag specification as tag: v${{package.version}}.
3. Example Add pax-utils into the OS. #2 (snyk-cli.yaml): Modified the git-checkout configuration by adjusting dependencies and keeping the explicit tag specification.

The key insight is that when using the git-checkout action in Melange, the tag parameter should correctly reference a Git tag rather than a branch. The current failure shows the same pattern - the build is trying to use a version tag (v0.20.4) but treating it as a branch.

Explanation

The build failure is occurring because the git-checkout step is incorrectly handling the tag reference. When examining the error message: "fatal: Remote branch v0.20.4 not found in upstream origin", it's clear that Git is trying to find a branch named 'v0.20.4' instead of looking for a tag.

The Melange git-checkout action needs to be configured correctly to handle tags. By specifying both branch: main and tag: v${{package.version}}, we instruct the build system to:

1. First clone the repository using the main branch as a starting point
2. Then checkout the specific tag

This approach works because:

1. It prevents Git from trying to directly check out a non-existent branch named 'v0.20.4'
2. It follows the proper Git workflow for checking out tags (first clone a branch, then checkout the specific tag)
3. It aligns with how similar issues were fixed in the example patches

The fix doesn't require changing the tag value itself since 'v0.20.4' appears to be the correct tag format for this repository (as confirmed by the update section which uses 'strip-prefix: v'). The issue is purely in how the git-checkout action is configured to handle the reference.

Alternative Approaches

• Set default_branch: main in the git-checkout action to specify the initial branch to clone before checking out the tag
• Modify the pipeline to use a custom git command with 'runs:' instead of the git-checkout action, explicitly controlling the clone and checkout process
• Use the fetch-depth parameter in git-checkout to ensure the tag is included in the fetched refs
