成功解决ubuntu-22.04的sudo apt-get update一直卡在【0% [Waiting for headers]】

问题描述

在下载安装包的时候一直卡在0% [Waiting for headers]，报错信息如下：

Get:1 file:/var/cudnn-local-repo-ubuntu1804-8.5.0.96 InRelease [1,575 B]

0% [Waiting for headers]

解决方案

sudo rm -rf /var/lib/apt/lists/* 
sudo rm -rf /var/lib/apt/lists/partial/*
cd /var/cache/apt/archives  
sudo rm -rf partial

以上命令都是清理缓存文件。

如果清除缓存文件之后还是遇到waiting for headers，那就更换国内源

#备份现有源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 

#查看当前版本
cat /etc/issue  

#修改文件，替换下面软件源，删除文件所有内容，替换对应版本的源，见Ubuntu国内源
sudo vim /etc/apt/sources.list 

#更新列表
sudo apt-get update

即在sudo vim /etc/apt/sources.list的这一步，将其中的内容全部注释掉。如下：

在前面没打#的地方加上#。

然后在最前面加上：（注意我的版本是ubuntu-22.04，其余版本参加下面链接。或者试一下也可以。）
