update-initramfs brakuje /lib/modules/4.4.0-13-generic

Właśnie zaktualizowałem linux-firmwarepakiet, a potem użyłem, $ sudo update-initramfs -u -k allale otrzymałem kilka błędów:

$ sudo update-initramfs -u -k all

Jestem pewien, że nie mam jądra 4.4.0-13. Mógłbym to mieć jakiś czas temu, ale go usunąłem:

$ apt list --installed | grep linux-

Jak naprawić te update-initramfsbłędy?

Narzędzie update-initramfswygląda var/lib/initramfs-tools. Znajdziesz tam wpis dla tego starego jądra. Usuwanie:

sudo rm /var/lib/initramfs-tools/4.4.0-13-generic

pozbędzie się tego błędu

(problem z ustawieniami regionalnymi to coś zupełnie innego ...)
