Title:
[24.10] Please test secure-boot and lockdown on the 6.11 kernel
(s390x) for Oracular
Status in Ubuntu on IBM z Systems:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Bug description:
The Canonical kernel team is working on a new 6.11 kernel for
'oracular' (24.10) and has an early build ready for secure-boot and
lockdown testing (version 6.11.0-4.4).
To avoid potentially negative implications that a broken secure-boot
lockdown functionality would cause (esp. using the production key), we
ask to get secure-boot tested early in the cycle using Canonical
kernel team's PPA key for signature.
The early test build is available at: ppa:canonical-kernel-team/unstable
(https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable/)
The PPA key used for signing can be found in the tarball available here:
https://ppa.launchpad.net/canonical-kernel-team/unstable/ubuntu/dists/devel/main/signed/linux-generate-unstable-s390x/current/
(Please note that this kernel is coming from the 'canonical-kernel-
team' PPA, hence it is NOT signed with the regular
archive/release/production key, instead with the above PPA's key!)
