安装 Linux Mint MATE 桌面后如何修复软件中心？

Question

我使用本手册安装了 MATE 桌面，但现在我无法打开我的 Ubuntu 软件中心，也无法从更新管理器打开设置。

我删除了队友桌面，但它并没有解决这个问题，我也重新安装使用该软件中心，软件-属性- GTK和软件特性，常见的有：
sudo apt-get update; sudo apt-get --purge --reinstall install software-center software-properties-common software-properties-gtk。

但是当使用这条线时，我收到以下错误：

有没有办法解决这个问题而不必重新安装 Ubuntu 11.10？？

Answer 1

我在软件中心和其他一些应用程序中遇到了同样的问题。但是，您不需要重新安装，尽管这可能为时已晚。这就是它不起作用的原因：

lsb_release -a

印刷：

Distributor ID: LinuxMint
Description: Linux Mint 12 Fluxbox
Release: 12
Codename: lisa

并且可以通过执行以下操作来纠正以保留 Mint-Mate：

gksu gedit /etc/*release

并将文件 gedit 中的所有内容更改为：

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=Oneric
DISTRIB_DESCRIPTION="Ubuntu 11.10"

然后运行：

gksu gedit /etc/*issue

并更改为：

Ubuntu 11.10 \n \l

虽然 Mate 的边缘看起来有点粗糙，但对我来说效果很好，但因为我纯粹是在 VBox 中测试 Oneric，所以没关系

Answer 2

_{将我的评论转换为答案}

这个升级过程类似于在 Natty 中使用 Gnome 3 PPA。

升级涉及升级到 300Mb+ 的软件库 - 这实际上是一个单向过程。

您可以在现有安装的顶部进行安装（因此保留现有的 /home 文件夹） - 但您需要重新安装所有其他应用程序。

尽管使用诸如 clonezilla/partimage 之类的东西先备份。
