A deployment to brennan a few days ago (via MAAS 2.4.2) succeeded, so I've done some re-testing today. Brennan continues to deploy successfully with Secure Boot active; however, systems in both 18T (I re-tested jehan and also tested feebas, a Cisco UCS C220 M4) and 1SS (I tested kies, a Supermicro SYS-6018U-TR4+) failed. Both 18T and 1SS have MAAS 2.6.2 servers.
