As mentioned previously, missing firmware isn't the only problem. Other main blockers are adding kernel modules (for example VirtualBox') and fwupd not working.
Am I right in understanding this as FDE/TPM won't really be supported "properly" for a good while yet and that people like myself relying on this should seek other alternatives until it's more mature? Meanwhile/alternatively: are there any workarounds like rolling one's own kernel snap with the necessary additions? Are there any guides available on doing that properly (especially related to getting the signing part done properly for Secure Boot to work)? Any way of contributing to solving this permanently BTW – sponsoring someone or doing actual work. Are these features (firmware component snaps, and similar for kernel modules) tracked somewhere? Lastly – is it possible to use FDE with TPM without using the snap kernel? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/2092363 Title: Missing (but referenced) SOF firmware in pc-kernel – No Audio Status in canonical-kernel-snaps: Confirmed Status in pc-kernel-snap: Invalid Status in apt package in Ubuntu: Invalid Status in boot-managed-by-snapd package in Ubuntu: Invalid Status in firmware-sof package in Ubuntu: Confirmed Status in linux package in Ubuntu: Invalid Bug description: I am encountering an issue with the pc-kernel snap on my HP EliteBook 840 G11 laptop running Ubuntu 24.04.1 LTS with the new TPM+FDE feature. Despite testing multiple kernel channels, the system fails to detect any audio devices. However, when booting into a live session of Ubuntu 24.04.1 LTS, audio functions as expected. This suggests the issue may be related to the pc-kernel snap. Right now I'm on channel 24/stable (version: 6.8.0-50.51), but I have tried 24-hwe/stable and 24.10/stable as well.
