[SOLVED] Kernel Panic Impish Indru

[Radcliff]

There's a Kernel panic after enabling Proposed (237 packages) in Kubuntu 21.10. Kernel 5.12.0 only with secure boot disabled. Must be removed, may have to do with Frameworks 5.81 updates.

dpkg --list | grep linux-image
ii  linux-image-5.11.0-16-generic                 5.11.0-16.17                                                         amd64        Signed kernel image generic
ii  linux-image-generic                           5.11.0.16.17                                                         amd64        Generic Linux kernel image
ii  linux-image-unsigned-5.12.0-051200-generic    5.12.0-051200.202104252130                                           amd64        Linux kernel image for version 5.12.0 on 64 bit x86 SMP

Mok manager got updated with regular updates (81) and not fixing the secure boot issue: Invalid signature for mainline Kernel, won't boot.

dpkg -l | grep mokutil
ii  mokutil                                       0.4.0-1                                                              amd64        tools for manipulating machine owner keys
dpkg -l | grep shim-signed
ii  shim-signed                                   1.46+15.4-0ubuntu1                                                   amd64        Secure Boot chain-loading bootloader (Microsoft-signed binary)

Lol. they barely have opened the archive for development, and breakages are guaranteed at this point. Probably nothing to do with libkf5 stuff at all. Ubuntu are still reworking the kernels, toolchains and other core bits, as well as the different desktop teams setting things up for the Flavours.


Finding and reporting this is huge waste of effort, at least here in KFN, and at this very early stage. Maybe an Ubuntu devel mailing list, an Ubuntu devel IRC/telegram channel list, or devel related Discourse may be more useful for this as actual Ubuntu devs would see it. No one but us chickens will see this here (for the most part), or be able to do anything about it, other than the usual wait-a day-its-still-being-built comments.

"Hey, the car won't start!"
"Well, yeah, the valves need to be adjusted on the new head, plus the battery is not hooked up.. Won't be driving it anyway, the transmission is over on the bench having some upgrades. "

To be honest, at this stage Ubuntu is still ripping out stuff, adding stuff in, upgrading tool chains, so things are missing or broken, which is actually very much expected.

LOL! (So the kernel is over on the bench, huh? )

Gone with the wind

I give it a second try after receiving the following:

2021-04-30 13:31:03 upgrade initramfs-tools:all 0.140ubuntu1 0.140ubuntu2
2021-04-30 13:31:03 upgrade initramfs-tools-core:all 0.140ubuntu1 0.140ubuntu2
2021-04-30 13:31:03 upgrade initramfs-tools-bin:amd64 0.140ubuntu1 0.140ubuntu2

Got it back to work:

uname -a
5.12.0-051200daily20210430-generic #202104292202 SMP Fri Apr 30 02:21:47 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Shim 1.47+15.4-0ubuntu2 fixes our secure boot issue 20210430.
