Agent Quick Fix

Repair against the current GitHub hosted Ubuntu image contract, then keep the change narrow and source-backed.

Product: GitHub hosted Ubuntu image
Current-contract area: Package name/repository availability differs on Ubuntu 24
Likely root cause: An apt install line that worked on 22.04 returns unable-to-locate-package.
Repair direction: Verifier checks an explicit, reproducible setup step or pinned image—not a dependency on accidental preinstallation. Require explicit setup/pinning that works on a fresh image.

Symptom

An apt install line that worked on 22.04 returns unable-to-locate-package.

Why This Happens

Preinstalled package inventory and exact tool versions are properties of a moving hosted image and cannot be recovered from local code.

Common Wrong Fixes

Changing local code without checking the current external contract.
Retrying the same install, build, or API call with no version/source change.
Applying a broad unsafe bypass when a narrow compatibility fix is available.
