So in general the key should be part of the firmware, in case of a standard IBM Power system, that is shipped to customers with secureboot support, A kernel from proposed is part of the official Ubuntu archive and with that signed with the standard production key. But that might be different in case a development system is in use or so ...
Anyway, the key can also be found at the Ubuntu archive pages: here: http://ports.ubuntu.com/ubuntu-ports/dists/focal/main/signed/linux-ppc64el/ http://ports.ubuntu.com/ubuntu-ports/dists/focal/main/signed/linux-ppc64el/current/signed.tar.gz or the link for proposed: http://ports.ubuntu.com/ubuntu-ports/dists/focal-proposed/main/signed/linux-ppc64el/ http://ports.ubuntu.com/ubuntu-ports/dists/focal-proposed/main/signed/linux-ppc64el/current/signed.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877955 Title: Fix for secure boot rules in IMA arch policy on powerpc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1877955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
