Dimitri, I note your comment #106 about secureboot patches upstream. If I recall correctly, a linux security update came down through Ubuntu Updater about the same time or just prior to the LTS 20.04.1 updates in mid September. A number of issues with LTS 20.04.1 appeared following two "batches" of September Ubuntu updates. To the extent that these issues may be inter-related -- at least insofar as being triggered by upstream Linux security change(s) -- please note the bug numbers listed in post #93 above.
If not relevant to this particular bug, then please disregard in deference to the other individual bug numbers; if inter-related, then perhaps this can be helpful. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed Status in OEM Priority Project: New Status in grub2 package in Ubuntu: Triaged Status in initramfs-tools package in Ubuntu: Invalid Status in linux package in Ubuntu: Invalid Bug description: "initramfs unpacking failed: Decoding failed", message appears on boot up. If I "update-initramfs" using gzip instead of lz, then boot up passes without decoding failed message. --- However, we currently believe that the decoding error reported in dmesg is actually harmless and has no impact on usability on the system. Switching from lz4 to gzip compression, simply papers over the warning, without any benefits, and slows down boot. Kernel should be fixed to correctly parse lz4 compressed initrds, or at least lower the warning, to not be user visible as an error.
