The integration jobs always run on a 24.04 runner, so the Juju model defaults to 24.04 even for the 26.04 platform matrix. Charmhub charms were therefore deployed at their 24.04 revision and could not be used with the locally built 26.04 MicroOVN charm: - the channel upgrades could not refresh across bases; - opentelemetry-collector 2/stable has no 26.04 revision and, as a subordinate, could not attach to the 26.04 principal. Deploy the channel charms with the base encoded in the packed charm name so they match the platform under test, and use the 0.130/stable collector track which publishes a 26.04 revision.

Channel charms were therefore deployed at their 24.04 revision and could not be used with the locally built 26.04 MicroOVN charm, leaving three integration jobs red on 26.04:test_upgrade_from_stable/test_upgrade_from_previous_lts: refresh failed withbase "ubuntu@24.04" not supported by charm, the charm supported bases are: ubuntu@26.04.test_cos_relation:opentelemetry-collector2/stable publishes no 26.04 revision, and as a subordinate it could not attach to the 26.04 principal.Fix:
