Hi I have a problem to install the new kernel 5.15 on my machine. To install the new kernel, I do this :

  • make menuconfig (I tried the cp .config method too) + modified lines to have no problem while the building (CONFIG_MODULE_SIG_KEY="", CONFIG_SYSTEM_TRUSTED_KEYS="", CONFIG_SYSTEM_REVOCATION_KEYS=""). Without this last step, I have some troubles with x509 certificates
  • make
  • sudo make install

When I do the last step, I have this :

mcarrere@silverstone:~/Téléchargements/linux-5.15$ sudo make install VERBOSE=1

Adding boot menu entry for UEFI Firmware Settings

I have no trouble while the "make".

What is the problem ? Is it usual to modify the .config for security keys ?

I need to install a kernel like this because I must modify the perf linux module and do some tests.

Thank you.

EDIT1 : So it's work now. I followed this topic and without changing my previous .config, it's work but I don't understand why it's work. An idea ? It's very curious...

ps : I did some tests on different kernels before, no need for the moment to remove them

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...
