问题升级11.04

Question

我一直试图升级我的ubuntu11.04桌面计算机，但是当我单击ugrade按钮时：

我知道这个错误：

我尝试更改我的存储库，但是它在错误中没有任何改变(在“设置新的软件通道”上)。

有人能给我指明正确的方向吗？

这是我的sources.list：

# deb http://ppa.launchpad.net/ailurus/ppa/ubuntu karmic main # disabled on upgrade to karmic
# deb-src http://ppa.launchpad.net/ailurus/ppa/ubuntu karmic main # disabled on upgrade to karmic

# newer versions of the distribution.

Answer 1

您需要从源列表或源list.d/*中删除任何与jaunty相关的存储库。

我之所以直截了当地大张旗鼓，是因为在您的截图中，失败的档案以jau作为发行版名称的开头。

它可能是查找deb-src http://pt.archive.ubuntu.com/ubuntu/ jaunty-backports main restricted universe multiverse，也可能是在您的源代码中有其他东西。

您可以使用像这这样的文本编辑器编辑/etc/ editor .如果你要编辑它，先复制一份。就像这个答案说的，你需要非常小心地编辑系统配置文件。

Answer 2

检查你是否可以平pt.archive.ubuntu.com，如果这不起作用.试着修改你的

/etc/apt/sources.list

删除"pt“的引用并保留"archive.ubuntu.com”。这将影响您的下载速度为新安装和更新，但它可能解决问题。
