我在 chroot 下运行 ARM ubuntu，一切似乎都设置好了，运行良好，但是当我去安装某些软件包时，我最终无法获取错误，这种情况并不会发生在所有情况下。例如，当我尝试安装 xfce4 时，我得到：

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

答案1
你正在运行哪个版本的 Ubuntu？ 已停产的移植版本已重命名。 我找到了一个讨论这里解释了解决方案：
1）备份/etc/apt/sources.list
2）假设您使用Raring（13.04），将内容替换为以下内容：
德布http://old-releases.ubuntu.com/ubuntu/raring 主宇宙受限多元宇宙
deb-src http://old-releases.ubuntu.com/ubuntu/狂热主宇宙受限多元宇宙德布http://old-releases.ubuntu.com/ubuntu/raring-security 主宇宙受限多元宇宙
deb-src http://old-releases.ubuntu.com/ubuntu/raring-security 主宇宙 受限多元宇宙德布http://old-releases.ubuntu.com/ubuntu/raring-updates 主宇宙 受限多元宇宙
deb-src http://old-releases.ubuntu.com/ubuntu/raring-updates 主宇宙 受限多元宇宙德布http://old-releases.ubuntu.com/ubuntu/raring-backports 主要受限宇宙多元宇宙

deb-src http://old-releases.ubuntu.com/ubuntu/提出的主要受限宇宙多元宇宙
3）运行apt-get update，它应该可以再次工作。
对我有用，希望它有帮助。
答案2
根据上面显示的输出，通常最好重新运行sudo apt-get update，然后再次尝试安装。ports.ubuntu.com 的缓存视图应该看上去软件包下载的内容与软件包的实际内容不匹配。
