Doh -- that one's my fault; included it in the kernel command line and completely forgot to include a patch in ubuntu-raspi-settings to add it to the set of modules for initramfs-tools to include in the initrd.
The workaround for now: $ sudo -i # echo zstd >> /etc/initramfs-tools/modules # echo z3fold >> /etc/initramfs-tools/modules # update-initramfs -u I'll try and get this added to ubuntu-raspi-settings shortly. ** Also affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New ** Also affects: initramfs-tools (Ubuntu Kinetic) Importance: Undecided Status: New ** Also affects: linux-raspi (Ubuntu Kinetic) Importance: Undecided Status: New ** Also affects: initramfs-tools (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-raspi (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: initramfs-tools (Ubuntu Kinetic) Assignee: (unassigned) => Dave Jones (waveform) ** Changed in: initramfs-tools (Ubuntu Jammy) Assignee: (unassigned) => Dave Jones (waveform) ** Also affects: ubuntu-settings (Ubuntu) Importance: Undecided Status: New ** No longer affects: initramfs-tools (Ubuntu) ** No longer affects: initramfs-tools (Ubuntu Kinetic) ** No longer affects: initramfs-tools (Ubuntu Jammy) ** Changed in: ubuntu-settings (Ubuntu Jammy) Assignee: (unassigned) => Dave Jones (waveform) ** Changed in: ubuntu-settings (Ubuntu Kinetic) Assignee: (unassigned) => Dave Jones (waveform) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-settings in Ubuntu. https://bugs.launchpad.net/bugs/1977764 Title: kernel modules "zstd" and "z3fold" missing.
