UOS换源

1、保存源文件

sudo cp -r /etc/apt/sources.list /etc/apt/sources.list.bak
1

2、更换源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
  
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

4、更新

sudo apt update
1

5、更新公钥

sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com

6、常见问题

由于出现了 “invalid packet” 的错误消息，可能是由于密钥文件本身的问题导致的。建议您尝试使用以下方法来解决该问题：

1. 删除 /etc/apt/trusted.gpg​ 文件：
   sudo rm /etc/apt/trusted.gpg
2. 创建一个新的空白 trusted.gpg​ 文件：
   sudo touch /etc/apt/trusted.gpg
3. 导入密钥：
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys
   注意，将 <KEY>​ 替换为您要导入的密钥的指纹。
4. 重复步骤3，为每个要导入的密钥重复该步骤。
