debian11 设置apt源为国内

  话不多说，直接上代码。将apt源设置为网易

cat > /etc/apt/sources.list << EOF
deb https://mirrors.163.com/debian/ bullseye main non-free contrib
deb-src https://mirrors.163.com/debian/ bullseye main non-free contrib
deb https://mirrors.163.com/debian-security/ bullseye-security main
deb-src https://mirrors.163.com/debian-security/ bullseye-security main
deb https://mirrors.163.com/debian/ bullseye-updates main non-free contrib
deb-src https://mirrors.163.com/debian/ bullseye-updates main non-free contrib
deb https://mirrors.163.com/debian/ bullseye-backports main non-free contrib
deb-src https://mirrors.163.com/debian/ bullseye-backports main non-free contrib
EOF

  执行命令：apt-get update
  查阅资料时，很多都是设置阿里云的源

cat > /etc/apt/sources.list << EOF
deb http://mirrors.cloud.aliyuncs.com/debian/ bullseye main contrib non-free
deb-src http://mirrors.cloud.aliyuncs.com/debian/ bullseye main contrib non-free

deb http://mirrors.cloud.aliyuncs.com/debian/ bullseye-updates main contrib non-free
deb-src http://mirrors.cloud.aliyuncs.com/debian/ bullseye-updates main contrib non-free

deb http://mirrors.cloud.aliyuncs.com/debian/ bullseye-backports main contrib non-free
deb-src http://mirrors.cloud.aliyuncs.com/debian/ bullseye-backports main contrib non-free

deb http://mirrors.cloud.aliyuncs.com/debian/ bullseye-proposed-updates main contrib non-free
deb-src http://mirrors.cloud.aliyuncs.com/debian/ bullseye-proposed-updates main contrib non-free

deb http://mirrors.cloud.aliyuncs.com/debian-security/ bullseye-security main contrib non-free
deb-src http://mirrors.cloud.aliyuncs.com/debian-security/ bullseye-security main contrib non-free
EOF

  更新dns，在配置文件中加入阿里巴巴提供的DNS域名解析，然而还是不行

sudo vim  /etc/resolv.conf
