Answer 2

看看https://launchpad.net/ubuntu/+mirror/mirrors.ispros.com.bd-archive ，孟加拉国的镜子似乎尚未使用Precise软件包进行更新。 您可能想要选择一个不同的附近镜像 （印度出现在我的脑海中）或提交有关它的错误。

Answer 3

您遇到的错误是因为该链接实际上已被删除。 这可能是暂时的，或者服务器可能无法正常运行或正在维护。（在您的情况下，包文件尚未上载到服务器上）
要解决此问题，请尝试更改下载源（根据服务器的不同，这可能有效，也可能无效）
开放software sources
单击ubuntu software选项卡
然后在选择其他的Download from ，然后单击select best server
之后，软件源将自动更新。
