python2.7：未找到：无法安装或删除任何软件包

我目前无法安装任何软件包。一开始它抱怨找不到/usr/bin/python（这里不确定路径），所以我尝试使用 synaptic 重新安装 python。重新安装也失败了。

现在，我无法访问 Unity 中的侧边栏，键盘快捷键也不起作用。我可以通过右键单击文件并选择“打开方式...”来访问 Chrome，并使用Alt- Ctrl-访问命令行f#，但仅此而已。

我做的sudo apt-get install结果是：

Reading package lists...
Building dependency tree...
Reading state information...
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 apturl : Depends: gconf2 (>= 2.28.1-2)
 gwibber : Depends: libgwibber-gtk2 (>= 3.1.4.1+r1119) but it is not installed
    Depends: libgwibber2 (>= 3.1.4.1) but it is not installed
 ibus : Depends: gconf2 (>= 2.28.1-2)
 libgksu2-0 : Depends: gconf2 (>= 2.28.1-2)
 update-manager : Depends: gksu but it is not installed

sudo apt-get -f install结果如下：

Do you want to continue [Y/n]? Setting up python-minimal (2.7.3-0ubuntu2) ...
/var/lib/dpkg/info/python-minimal.postinst: 4: /var/lib/dpkg/info/python-minimal.postinst: python2.7: not found
dpkg: error processing python-minimal (--configure):

任何帮助都很好。看来我彻底完蛋了。

我检查了我的/usr/bin directory：

lrwxrwxrwx 1 nolando nolando 9 Apr 17  2012 python -> python2.7  
lrwxrwxrwx 1 nolando nolando 9 Apr 17  2012 python2 -> python2.7

我正在使用 12.04。

答案1

哦，解压 python .deb 时出了严重错误。尝试dpkg -i /var/cache/apt/archives/python2.7-minimal*deb看看是否能修复 dpkg 错误。

答案2

这里有类似的问题http://ubuntuforums.org/showthread.php?t=1721421由于 python 具有广泛的依赖性，因此通过重新安装解决了这个问题。

但请尝试使用此论坛的解决方案http://ubuntuforums.org/showthread.php?t=1425619，它可能只是关于 python 配置和版本

尝试一下/usr/bin/python，如果结果很奇怪，请给我们留言或尝试手动查找 python。也许符号链接就足够了。
