Motivation

Ubuntu release codenames cannot be derived from version numbers, so the edge router currently needs a code change for every Ubuntu release.

The generic repository setup can already read VERSION_CODENAME from /etc/os-release and send it in the user agent.

Changes

  • Prefer a strictly validated codename=<name> token for Ubuntu slot routing.
  • Retain the existing version-to-codename table for clients using the previous user-agent format.
  • Add a future Ubuntu 28.04 regression case whose codename does not exist in the middleware table.

User-agent format

R/4.6.1 (Ubuntu 26.04; codename=resolute) (aarch64-unknown-linux-gnu)

Verification

  • just edge-test, 1 test with 16 steps passed.
  • git diff --check
