刚开始在我的digitalocean液滴上重新安装Ubuntu 14.04，我试图安装git 。
我的第一次尝试未能安装一些软件包 –
root@Jedi:~# sudo apt-get install git-all ... ... E: Failed to fetch http://mirrors.digitalocean.com/ubuntu/pool/main/g/gcc-4.8/libgomp1_4.8.4-2ubuntu1~14.04.1_amd64.deb 404 Not Found [IP: 95.85.0.50 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
所以我采取了上面的build议，并重新运行它--fix-missing修复， --fix-missing希望能解决它。 没有运气 – 仍然缺less下面提到的包。
它试图安装的软件包究竟是什么，为什么它在一张fesh操作系统映像上失败？ 运行which git没有返回，这告诉我没有安装。
谢谢！

有时候， 强制全面刷新可以帮助 ：
sudo apt-get clean cd /var/lib/apt sudo mv lists lists.old sudo mkdir -p lists/partial sudo apt-get clean sudo apt-get update
嗯…我再次运行相同的原始命令
sudo apt-get install git-all
它神奇的工作
唉…不可重现的错误是最糟糕的一种-_-
