首先，我是 ubuntu 的菜鸟。我需要运行一个 Java 应用程序并安装了最新版本。之后，尝试运行 .jar 文件，成功了，但当我尝试运行已安装的文件时，它们给我一个错误，说应用程序是 32 位的，而我的 java（和 ubuntu）安装是 64 位的。在谷歌上搜索了一段时间后，我发现我需要安装 icedtea。尝试这样做，但没有成功。
sudo apt-get clean
sudo apt-get autoremove
给我

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
icedtea-6-plugin:i386 : Depends: icedtea-netx:i386 (= 1.5-1ubuntu1) but it is not installable
E: Unmet dependencies. Try using -f.
然后尝试
sudo apt-get -f autoremove
并让我回归

尝试过
sudo apt-get update
还是同样的问题。
关于如何通过控制台删除此包及其依赖项，您有什么想法吗？或者，如果不可能，如何手动删除它们？
提前致谢！Pablo
答案1
尝试这个
sudo-i
dpkg -i --force-overwrite /var/cache/apt/archives/icedtea-netx_1.5-1ubuntu1_i386.deb apt-get autoremove apt-get update apt-get upgrade
答案2
它清楚地说“sudo apt-get -f install”，但之后没有任何提示。这将自动清除不需要的软件包，然后您就可以开始了。相信我，它对我有用。
