我正在使用 32 位 Ubuntu 12.04，内核为 3.2.0-26-generic，GNOME 为 3.4.1。
当我运行升级管理器时，我得到了部分升级的选项，并显示详细信息：
install (11)
remove (1)
upgrade (744)
然后我开始升级并得到：
Could not download the upgrades
The upgrade has aborted. Please check your Internet connection or installation media and try again. All files downloaded so far have been kept.
Where out of 755 files. It does not download 5:

这似乎是尼泊尔镜像的问题，请尝试按照说明更改下载服务器我怎样才能使用靠近我的镜像，或者选择更快的镜像？
