Seeing the same issue on a Hyper-V VM running 20.04. Workaround is to enroll the MOK with mokutil.
Seems related to this bug: https://github.com/rhboot/shim/issues/143 . While it was closed in 2018, maybe no one has recompiled shim-signed with the fixed gnuefi? ** Bug watch added: github.com/rhboot/shim/issues #143 https://github.com/rhboot/shim/issues/143 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870955 Title: MokManager - Only DER encoded certificate (*.cer/der/crt) is supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1870955/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
