Hi, please reply to the list debian-user@lists.debian.org instead to me in private. (I'm subscribed there. No need to Cc: me.)
Since i seem to be the only responder who send you a Cc: , i wanted to point you to the other answers to your initial mail in the list archives. But https://lists.debian.org/debian-user/ does not deliver a page, although ping lists.debian.org works fine. Are alternative archive URLs known ? E.g. to USENET linux.debian.user ? The content of your in-private reply does not look like it is confidential. So i quote from it publicly.

The boot firmware (EFI ?) and GRUB obviously don't do what is needed. > Recent history: > More than a month ago, keyboard become unusable after upgrade. > But, last week, an upgrade solved the problem: > --------------------------------------------------------------- > Start-Date: 2025-07-04 07:41:06 > Commandline: apt upgrade > Requested-By: g (1000) > Upgrade: libvirt-common:amd64 (11.3.0-2, 11.3.0-3), libperl5.40:amd64 > (5.40.1-3, 5.40.1-5), libvirt-daemon-driver-storage-logical:amd64 (11.3.0-2, > 11.3.0-3), libvirt-daemon-config-nwfilter:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-driver-xen:amd64 (11.3.0-2, 11.3.0-3), perl:amd64 (5.40.1-3, > 5.40.1-5), libvirt-daemon:amd64 (11.3.0-2, 11.3.0-3), ibus-gtk3:amd64 > (1.5.32-1, 1.5.32-2), ibus-gtk4:amd64 (1.5.32-1, 1.5.32-2), > firefox-nightly:amd64 (142.0a1~20250702212902, 142.0a1~20250703203803), > python3-ibus-1.0:amd64 (1.5.32-1, 1.5.32-2), > libvirt-daemon-driver-storage-disk:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-plugin-lockd:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-driver-storage-iscsi:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-driver-nodedev:amd64 (11.3.0-2, 11.3.0-3), > grub-efi-amd64-unsigned:amd64 (2.12-8, 2.12-9), libvirt-daemon-lock:amd64 > (11.3.0-2, 11.3.0-3), libvirt0:amd64 (11.3.0-2, 11.3.0-3), > grub-efi-amd64:amd64 (2.12-8, 2.12-9), libvirt-daemon-driver-nwfilter:amd64 > (11.3.0-2, 11.3.0-3), libvirt-daemon-driver-vbox:amd64 (11.3.0-2, 11.3.0-3), > gir1.2-ibus-1.0:amd64 (1.5.32-1, 1.5.32-2), ibus-data:amd64 (1.5.32-1, > 1.5.32-2), libvirt-daemon-driver-qemu:amd64 (11.3.0-2, 11.3.0-3), > grub-efi-amd64-signed:amd64 (1+2.12+8, 1+2.12+9), libvirt-clients:amd64 > (11.3.0-2, 11.3.0-3), libvirt-daemon-common:amd64 (11.3.0-2, 11.3.0-3), > anydesk:amd64 (7.0.0, 7.0.1), libvirt-daemon-log:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-driver-secret:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-config-network:amd64 (11.3.0-2, 11.3.0-3), libvirt-l10n:amd64 > (11.3.0-2, 11.3.0-3), gnome-control-center-data:amd64 (1:48.2-2, 1:48.3-3), > libvirt-daemon-driver-interface:amd64 (11.3.0-2, 11.3.0-3), > grub-efi-amd64-bin:amd64 (2.12-8, 2.12-9), grub2-common:amd64 (2.12-8, > 2.12-9), plasma-nm:amd64 (4:6.3.4-1, 4:6.3.4-2), perl-base:amd64 (5.40.1-3, > 5.40.1-5), grub-common:amd64 (2.12-8, 2.12-9), > libvirt-daemon-driver-network:amd64 (11.3.0-2, 11.3.0-3), ibus-gtk:amd64 > (1.5.32-1, 1.5.32-2), gnome-control-center:amd64 (1:48.2-2, 1:48.3-3), > ibus:amd64 (1.5.32-1, 1.5.32-2), libvirt-daemon-system:amd64 (11.3.0-2, > 11.3.0-3), perl-modules-5.40:amd64 (5.40.1-3, 5.40.1-5), > libvirt-daemon-driver-storage-mpath:amd64 (11.3.0-2, 11.3.0-3), > libibus-1.0-5:amd64 (1.5.32-1, 1.5.32-2), > libvirt-daemon-driver-storage-scsi:amd64 (11.3.0-2, 11.3.0-3), > libvirt-daemon-driver-lxc:amd64 (11.3.0-2, 11.3.0-3) > End-Date: 2025-07-04 07:41:35 > --------------------------------------------------------------- > > The keyboard and the mouse worked well, but two days later, after the > another upgrade > ---------------------------------------------------------------------------- > ----- > Start-Date: 2025-07-06 09:27:29 > Commandline: apt upgrade > Requested-By: g (1000) > Upgrade: firefox-nightly:amd64 (142.0a1~20250704212032, > 142.0a1~20250705211551), firmware-sof-signed:amd64 (2025.01-1, 2025.05-1), > mobile-broadband-provider-info:amd64 (20240407-1, 20250613-2) > End-Date: 2025-07-06 09:27:35 > ---------------------------------------------------------------------------- > ----- > > the keyboard and the mouse are, again, not available at boot. > Any thought about firmware-sof-signed package? Debian's package info infrastructure is unresponsive too: https://packages.debian.org/unstable/firmware-sof-signed So: https://launchpad.net/ubuntu/plucky/+package/firmware-sof-signed "Intel SOF firmware - signed Provides the Intel SOF audio firmware and topology needed for audio functionality on some Intel system." This does not look overly suspicious for sabotaging a keyboard. Have a nice day :) Thomas
