我正在进行正常更新（Ubuntu 10.10，64 位），软件更新失败。软件中心抛出错误“无法安装项目...想要修复”？我按下修复按钮，然后出现错误“包操作失败”。
我在网上查找了一下，发现了一些可以尝试的事情：
**sudo apt-get install -f**

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
icedtea6-plugin : Depends: openjdk-6-jre (= 6b20-1.9.10-0ubuntu1~10.10.2) but 6b20-1.9.10-0ubuntu1~10.10.3 is installed
E: Unmet dependencies. Try using -f.
**sudo apt-get clean**
**sudo apt-get install -f**
(same error as above)
我可以看到 openjdk 的依赖项已损坏，但我不知道下一步该怎么做才能真正修复该问题。我需要在我的计算机上安装其他软件，这让我很头疼。
有任何想法吗？

几天前我以某种方式解决了这个问题，但不清楚我是怎么做到的。无论如何，今天升级时问题再次出现。我找到了一个日语网站，上面显示了答案：
$ which update-alternatives
/usr/bin/update-alternatives
$ sudo which update-alternatives
/usr/local/bin/update-alternatives
$ sudo mv /usr/local/bin/update-alternatives /usr/local/bin/update-alternatives.old
$ sudo apt-get upgrade

Setting up flashplugin-installer (11.1.102.62ubuntu0.10.10.2) ...

因此，总而言之，有两种不同的更新替代方案，我只需要确保它运行的是“正确的”方案。
