Kernel Linux 5.15.15 ou 5.16.11 no Debian 11 Bullseye

Atualizar o Kernel é algo muito especifico e só deve ser feito se o seu hardware pede uma versão mais atual, se é o seu caso confira como ter o Linux 5.15.15 ou 5.16.11 no Debian 11 Bullseye.

Kernel

Em computação, o núcleo ou kernel é o componente central do sistema operativo da maioria dos computadores; ele serve de ponte entre aplicativos e o processamento real de dados feito a nível de hardware. As responsabilidades do núcleo incluem gerenciar os recursos do sistema. Wikipédia

 

O kernel padrão do Debian 11 Bullseye é o 5.10 e só ira receber atualizações de segurança.

 

 

 

Se por algum motivo você precisa de uma versão do kernel Linux mais atual no Debian, precisa habilitar o repositório backports.

 Confira o que a documentação nos fala sobre esse repositório.

"Você está executando o Debian estável, porque prefere a versão estável do Debian. Funciona muito bem, só há um problema: o software está um pouco desatualizado em comparação com outras distribuições. É aqui que entram os backports."

 Origem dos pacotes do backports:

"Backports são pacotes retirados do próximo lançamento do Debian (chamado "Testing"), ajustados e recompilados para uso no Debian estável. Como o pacote também está presente na próxima versão do Debian, você pode facilmente atualizar seu sistema estável + backports assim que a próxima versão do Debian for lançada. (Em alguns casos, geralmente para atualizações de segurança, backports também são criados a partir da distribuição instável do Debian.)"

Fonte

 

Para habilitar o backports abra a sua sources.list e cole a linha abaixo no final da sources.list.

 

 deb http://deb.debian.org/debian bullseye-backports main

su -

nano /etc/apt/sources.list

Ficando como na imagem.

 

 

 

Salve teclando ctrl + x tecle s e tecle Enter para fechar.

Atualize a lista de pacotes.

apt update

Instale o kernel da sua preferência.

 

Kernel 5.15.15

 

apt install linux-image-5.15.0-0.bpo.3-amd64 linux-headers-5.15.0-0.bpo.3-amd64

Ou

 

Kernel 5.16.11

 

apt install linux-image-5.16.0-0.bpo.3-amd64-unsigned  linux-headers-5.16.0-0.bpo.3-amd64

 

 Feita a instalação basta reiniciar o sistema.

Para procurar por novas versões do kernel use o comando abaixo.

apt search linux-image

No quadro abaixo temos todos os kernels disponiveis para o Debian 11.
