[Bug 2142693] [NEW] [26.04] Please test secureboot and lock-down with 7.0.0 kernel (s390x) on Resolute Raccoon

Public bug reported:

The Canonical kernel team is working on an early 7.0.0 kernel for Ubuntu
Resolute Raccoon (26.04) and has an early build ready for secure-boot
and lockdown testing (version 7.0.0-1.1).

https://launchpad.net/~canonical-kernel-
team/+archive/ubuntu/unstable/+packages?field.name_filter=&field.status_filter=published&field.series_filter=resolute

To avoid potentially negative implications that a broken secure-boot
lockdown functionality would cause (esp. using the production key), we
kindly ask to get secure-boot tested, using Canonical kernel team's PPA
key for signature.

The linux-generic (7.0.0-1.1 or actually latest) is available in ppa:canonical-kernel-team/unstable.
(https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable)

$ sudo add-apt-repository ppa:canonical-kernel-team/unstable # add the unstable kernel PPA
$ sudo apt update # if not done automatically after the previous command
$ apt-cache policy linux-generic # will show potential install candidates
$ sudo apt install linux-generic=7.0.0-1.1 # install explicit version; or just latest available

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, BUT instead with the above PPA test signing key.
