Unfortunately the automated stable backport to v5.4, v5.10, and v5.14 failed because the source file that is modified by this patch was moved around: https://lore.kernel.org/stable/[email protected]/ > But since this bug is marked as critical, the patch is relatively short, > traceable and s390x-specific, I'll go ahead and submit this patch for Jammy > and Focal ahead of upstream stable. In addition to the work you plan, I could provide an adjusted stable backport for the upstream targets for which automatic backport failed. Would this help get this patch into any more Ubuntu versions? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1996071 Title: [UBUNTU 20.04] boot: Add secure boot trailer Status in Ubuntu on IBM z Systems: New Status in linux package in Ubuntu: Invalid Status in linux source package in Focal: New Status in linux source package in Jammy: New Status in linux source package in Kinetic: New Bug description: Description: boot: Add secure boot trailer Symptom: Secure boot of Linux will no longer be possible with an upcoming IBM Z firmware update.
