系统更新

更新时报错一些源找不到(这个后来发现是因为配置网关配错了，没关系 就当一次实验了)

sudo apt update && sudo apt upgrade -y

尝试换源：

(1) 备份源文件

sudo cp /etc/apt/sources.list.d/ubuntu.sources /etc/apt/sources.list.d/ubuntu.sources.bak

(2) 替换为阿里云源

sudo vim /etc/apt/sources.list.d/ubuntu.sources

清空原有内容，粘贴以下阿里云源（适用于 Ubuntu 22.04 LTS,YAML格式） ：

Types: deb
URIs: http://mirrors.aliyun.com/ubuntu
Suites: noble noble-updates noble-backports noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

原有的内容：

重新更新系统：

# 清除旧的源缓存
sudo apt clean && sudo apt autoclean

# 重新更新源并升级
sudo apt update && sudo apt upgrade

scsi host6: Fusion MPT SAS Host 这句服务器主板上，没有普通的 SATA 接口，而是搭载了 SAS 阵列卡（Fusion MPT SAS），这个是企业级服务器的标配；

最后排查的原因是硬件SAS口没有安装~ 这这~ 属实没想到。
