安装Linux Mint MATE桌面后如何修复软件中心？

我使用本手册安装了MATE桌面，但是现在我无法打开Ubuntu软件中心，也无法通过更新管理器打开设置。

我删除了mate桌面，但不能解决问题，我还使用以下命令重新安装了软件中心，software-properties-gtk和software-properties-common
sudo apt-get update; sudo apt-get --purge --reinstall install software-center software-properties-common software-properties-gtk。

但是当使用此行时，出现以下错误：

有没有一种方法可以解决此问题而不必重新安装Ubuntu 11.10？

在此先感谢tinuz

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，虽然这可能为时已晚，但您无需重新安装。这就是为什么它不起作用的原因：

lsb_release -a

印刷品：

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

可以通过以下操作将其更正以保留Mint-Mate：

gksu gedit /etc/*release

并更改gedit带来的文件中的所有内容：

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

尽管对我来说Mate看起来有些粗糙，但对我来说效果很好，但是由于我在VBox中纯粹测试Oneric

_{将我的评论转换为答案}

此升级过程类似于Natty中Gnome 3 PPA的使用。

升级涉及升级到300Mb +的软件库-这实际上是一种单向过程。

您可以将其安装在现有安装的顶部（从而保留现有的/ home文件夹）-但您需要重新安装所有其他应用程序。

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

我尝试重置lsb-release和* issue，但是由于某些原因，它们始终恢复为Linux mint。我不确定它们是否在每次重新启动或每次更新时重置，但是它们确实会频繁重置。

我写了一个小脚本，不时手动运行：

#!/bin/sh

echo "Restoring /etc/lsb-release ..." && \
echo "DISTRIB_ID=Ubuntu" > /etc/lsb-release && \
echo "DISTRIB_RELEASE=11.10" >> /etc/lsb-release && \
echo "DISTRIB_CODENAME=oneiric" >> /etc/lsb-release && \
echo "DISTRIB_DESCRIPTION=Ubuntu 11.10" >> /etc/lsb-release && \
echo "Restoring /etc/*issue ..." && \
echo "Ubuntu 11.10 \\n \\l" > /etc/*issue && \
echo "Done."

另存为（例如）fixubuntu.sh并对其设置执行权限（chmod 755 fixubuntu.sh），并在每次要恢复ubuntu发布信息时以root用户身份执行（sudo ./fixrelease.sh）。

当然，您可能希望在每次启动时自动运行脚本。只要确保它以root身份运行即可。
