Problemas sem fio RLT 8822BE

Question

teve alguns problemas com o driver RTL 8822BE. Eu já tenho o kernel 4.14 ( link ). Mas parece haver um problema:

$ lspci -knn | grep Net -A3

O método do toadjamb ( ubuntu 16.04 sobre inveja hp ae000 problemas wi-fi ) me dá em um certo ponto:

 $ sudo make install
make -C /lib/modules/4.14.0-041400-generic/build M=/home/multiple/rtlwifi-next modules
make[1]: *** /lib/modules/4.14.0-041400-generic/build: No such file or directory.  Stop.
Makefile:100: recipe for target 'all' failed
make: *** [all] Error 2

$ sudo modprobe -r rtl8822be
modprobe: FATAL: Module rtl8822be not found.

I have securityboot swiched off in BIOS. Don't know what to to...

Alguém tem um conselho?

Saudações  Lui

O diretório 'build' ausente geralmente sugere que o pacote de cabeçalhos do Linux necessário para compilar os módulos não está instalado. Verifique:

sudo dpkg -s linux-headers-4.14.0-041400-generic

Se você achar, como suspeitamos, que o pacote não está instalado, faça o download e instale-o. Eu suponho que você obteve a imagem do kernel 4.14.0-041400-genérico aqui: link

Por favor, selecione o arquivo .deb apropriado para sua arquitetura, seja 32 ou 64 bits, instale-o e tente a compilação rtl8822be novamente.
