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：

0% Waiting for headers
解决方案
python
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
python
#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。）
