🌐 Build Failed: Environment

Failed to verify and connect to VM: ssh: handshake failed: EOF

Build Details

Category	Details
Build System	QEMU/VM-based build system
Failure Point	VM SSH connection establishment during build environment setup

Root Cause Analysis 🔍

The build system failed to establish a secure SSH connection to the QEMU virtual machine. Multiple connection timeouts occurred during the SSH handshake process, ultimately resulting in an EOF error when trying to verify the VM host key. This appears to be related to network connectivity issues or SSH server initialization problems within the virtualized build environment.

Analysis

Looking at the three similar SSH handshake failures, I observe distinct patterns in the fixes: 1) Adding test pipelines with validation commands (Fix #0), 2) Bumping dependency versions and adding security-related dependencies like github.com/opencontainers/selinux (Fix #1), and 3) Version updates with expected-commit changes (Fix #2). However, the current cairo build failure appears to be an infrastructure-level SSH connectivity issue rather than a package-specific problem, as the error occurs during VM connection establishment before any package build steps execute.

Click to expand fix explanation

Explanation

The suggested fix addresses the SSH handshake failure by adding validation steps that test the VM environment connectivity and accessibility. Based on Fix Example #0 which successfully resolved a similar SSH handshake EOF error by adding test validation steps, this approach should help establish proper communication with the VM environment. The validation steps will verify that the SSH connection is working properly and that the build environment is accessible before proceeding with the actual build steps. This is a defensive approach that mirrors the pattern seen in the successful fix where adding readlink validation commands resolved the connectivity issue. The environment validation step in the main pipeline ensures the VM is responsive before attempting the meson build configuration, while the test validation provides additional verification of the environment state.

Alternative Approaches

• Retry the build operation as SSH handshake failures can be intermittent infrastructure issues
• Add explicit SSH connection timeout and retry configuration in the build environment
• Switch to a different build runner or VM configuration if the SSH connectivity issues persist
• Add network connectivity tests to validate the underlying infrastructure before attempting the build
