我有 Dell Latitude E6430，系统信息：Ubuntu 11.10，操作系统类型 64 位。当我尝试更新我的 Ubuntu 11.10 时，它给了我一条消息，除非您删除第三方存储库，否则您无法更新任何内容，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.
When writing the command sudo apt-get install -f , the following appear

答案1
问题在于您的软件索引已损坏。某个软件包或其他软件包存在问题。如果您使用apt-get，则很可能无法正常工作。尝试以下操作：
- 输入
sudo dpkg --configure -a。它会出错，但不用担心。 - 找到导致问题的文件并键入
sudo dpkg -r PACKAGE_NAME每个文件以将其删除。有些文件将无法删除。将它们添加到列表中。 sudo dpkg --configure PACKAGE_NAME对列表中的每个包运行。它将配置它们。这次，你不应该看到任何错误。- 运行
sudo apt-get install -f以修复依赖关系。 - 利润！
另外，您可能希望运行sudo apt-get autoremove以删除不必要的软件包。祝你好运！
更新：要修复该问题ldconfig，请尝试以下操作：
aptitude download libc-bindpkg-deb -x libc-bin* libc_unpackedcp libc_unpacked/sbin/ldconfig* /sbin/
