FWIW, a partner is also hitting this in the field when trying to do Secure Boot installs which break 100% of the time for them.
They have noted, however, that installing from ISO works and can successfully install and boot on a secure boot enabled server. They've only tested Focal ISOs at this time, but this tells me that there's some difference between what MAAS images are getting or have gotten, and what the ISO has or is doing during install. ** Tags added: blocks-hwcert-server -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1865515 Title: Chainbooting from grub over the network to local shim breaks chain of trust To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1865515/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
