更新和升级ubuntu 11.10
我有戴尔纬度E6430，系统信息：Ubuntu 11.10，OS类型64位。 当我试图对我的Ubuntu 11.10进行更新时，它给了我一条消息，除非您删除第三方存储库，否则无法更新任何内容，但您可以进行升级。 消息1：
your Ubuntu release is not supported anymore. you will not get any further security fixes or critical updates. please upgrade to a later version of Ubuntu Linux. 消息2：
not all updates can be installed. run a partial upgrade, to install as many updates as possible. this can be caused by : a previous upgrade which didn't complete. problems with some of the installed software. unofficial software packages not provided by Ubuntu. normal changes of a pre-release version of Ubuntu. I clicked on partial upgrade and it prepares upgrade for three hours then start to upgrade , then it didn't finish and stops then these message appear. message 3: software index is broken . it is impossible to install or remove any software. please use the package manager "synaptic" or run " sudo apt-get install-f " in a terminal to fix this issue at first.

问题是您的软件索引已损坏。 某些包裹或其他包装存在问题。 如果你使用apt-get ，它很可能无法正常工作。 试试这个：
- 输入
sudo dpkg --configure -a。 它会出错，但不要担心。 - 找到导致问题的文件，并为每个文件键入
sudo dpkg -r PACKAGE_NAME以将其删除。 其中一些将无法删除。 将它们添加到列表中。 - 运行
sudo dpkg --configure PACKAGE_NAME为列表中的每个包配置sudo dpkg --configure PACKAGE_NAME。 它将配置它们。 这一次，您不应该看到任何错误。 - 运行
sudo apt-get install -f来修复依赖项。 - 利润！
此外，您可能希望运行sudo apt-get autoremove来删除不必要的包。 祝好运！
更新：要解决ldconfig的问题，请尝试以下操作：
-
aptitude download libc-bin -
dpkg-deb -x libc-bin* libc_unpacked -
cp libc_unpacked/sbin/ldconfig* /sbin/
