Install a new kernel: missing /lib/modules

Solution 1:

So it's ok with this topic :

$ sudo make menuconfig
change some lines in the .config :
CONFIG_MODULE_SIG_KEY=""
CONFIG_SYSTEM_TRUSTED_KEYS=""
CONFIG_SYSTEM_BLACKLIST_HASH_LIST=""
CONFIG_SYSTEM_REVOCATION_KEYS=""
$ sudo make clean
$ sudo rm -rf debian
$ rm -f vmlinux-gdb.py
$ sudo make -j$(nproc) deb-pkg
$ cd ..
$ sudo dpkg -i linux-*.deb
$ awk -F\' '$1=="menuentry " || $1=="submenu " {print i++ " : " $2}; /\tmenuentry / {print "\t" i-1">"j++ " : " $2};' /boot/grub/grub.cfg
$ sudo update-grub

Maybe It's not very clean for the encryption part but it's work. If someone has a better idea...
