ubuntu更换国内阿里镜像源

Ubuntu 默认源是国外地址不仅可能找不到包还会导致下载慢。我们将源替换为阿里云 Ubuntu 源稳定且速度快1. 备份原有源文件防止改错# 备份sources.list文件 cp /etc/apt/sources.list /etc/apt/sources.list.bak # 更换镜像源为阿里源 # https://developer.aliyun.com/mirror/ubuntu?spma2c6h.13651102.0.0.3e221b11hDl7dS2. 编辑源文件用 vim 修改# 打开源配置文件 vim /etc/apt/sources.list3. 替换源内容清空原有内容粘贴以下内容先按Esc进入 Vim 普通模式输入:%d回车清空所有内容再按i进入插入模式粘贴对应 Ubuntu 版本的源先确认你的 Ubuntu 版本先确认 Ubuntu 版本执行以下命令lsb_release -c rootDESKTOP-KHJGL5C:/etc/apt# lsb_release -c Codename: jammy # 输出示例Codename: jammy代表Ubuntu 22.04如果是Ubuntu 22.04 (jammy)粘贴deb
