Bom dia! Eu sou um novato no Linux e eu tenho tentado instalar uma versão do kernel diferente da que veio com a minha distribuição do Ubuntu (16.04.4 LTS). Configurando e construindo o kernel (4.15.7) ambos funcionam bem, mas quando eu tento instalá-lo (sudo make install) eu sempre recebo os seguintes avisos e acabo não conseguindo inicializar no novo kernel. Eu procurei na internet e tentei as soluções sugeridas, mas ainda não consegui resolver. Isso é o que eu recebo quando eu executo o sudo make install
sh ./arch/x86/boot/install.sh 4.15.7 arch/x86/boot/bzImage \
System.map "/boot"
