无法将 Trusty 14.04.1 升级到 14.04.2 HWE

Question

我发出了在https://wiki.ubuntu.com/Kernel/LTSEnablementStack 上找到的命令字符串并得到了这个结果：

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

如果出现此问题，则您必须使用 Ubuntu 软件中心或 apt-get 卸载这些软件包。

要使用 Ubuntu 软件中心：单击任务栏上的图标或使用 Super 键并键入Ubuntu Software Navigate to the Installed packages 并找到搜索栏，然后为每个错误提供包键入并卸载它们。

使用终端（apt-get）

sudo apt-get autoremove packages | apt-get autoclean
sudo apt-get purge
sudo apt-get update

这确保没有留下任何东西。

还要等待来自软件中心更新程序的 Mesa 更新。然后删除libqt5gui5

需要删除的包如下

account-plugin-facebook
account-plugin-google
libqt5gui5

此时使用维基给出的命令并安装。

注意：如果有其他包安装涉及此问题，则使用 apt-get 命令专门使用这些包的名称。
