Pull request overview

Updates the Inspektor Gadget (ig) package versions used by AgentBaker’s VHD builder (via components.json) and aligns the separately-managed ig-gadgets package versions used during image build.

Changes:

• Bump ig package versions in parts/common/components.json to 0.52.0 for Ubuntu 20.04/22.04/24.04 and Azure Linux 3.0.
• Bump ig-gadgets package versions in vhdbuilder/packer/install-ig.sh to 0.52.0 for DEB/RPM installs.
• Remove a ShellSpec test block that previously validated ig_validate_version_compatibility.

Package Update Analysis: inspektor-gadget (ig)

Version change: 0.51.0-* → 0.52.0-* (minor update)
OS variants affected: Ubuntu 24.04, Ubuntu 22.04, Ubuntu 20.04, Azure Linux 3.0
OS variants NOT updated: None — full coverage

Changes between 0.51.0 and 0.52.0

Upstream changelog/release notes are not referenced in-repo for this version range, so specific behavior changes cannot be verified from the provided materials. Manual validation (at least VHD build + linux-vhd-content-test.sh coverage that exercises IG artifact checks) is recommended before merge.

Overall Risk: 🟡 Medium

Recommendation: Request more info / ensure validation runs (especially because IG includes eBPF artifacts and is validated during VHD content tests).
