我有Ubuntu 14.04（内核 3.19.0-49）并且我想安装最新的 LTS 支持堆栈来访问内核 4+。
根据维基百科， 我需要去做
$ sudo apt-get install --install-recommends linux-generic-lts-wily xserver-xorg-core-lts-wily xserver-xorg-lts-wily xserver-xorg-video-all-lts-wily xserver-xorg-input-all-lts-wily libwayland-egl1-mesa-lts-wily

E: Unable to correct problems, you have held broken packages.
但我遇到了未满足的依赖关系。
为什么？我该怎么办？
谢谢。

不幸的是，我无法独自安装推荐的软件包。
$ sudo apt-get install libgl1-mesa-glx-lts-wily
[...]
The following packages have unmet dependencies:
libgl1-mesa-glx-lts-wily : Depends: libglapi-mesa-lts-wily (= 11.0.2-1ubuntu4~trusty1) but it is not going to be installed
Depends: libgl1-mesa-dri-lts-wily (>= 7.2) but it is not going to be installed
如果我尝试安装
$ sudo apt-get install libglapi-mesa-lts-wily
The following packages have unmet dependencies:
libglapi-mesa-lts-wily : Conflicts: libglapi-mesa
Conflicts: libglapi-mesa:i386

不幸的是，安装了 LTE HWE 后系统无法启动。系统在启动时卡住，无法进入登录屏幕。
我通过从头开始重新安装 Ubuntu 14.04.4 来“解决”。
答案1
正确的命令是
sudo apt-get install linux-generic-lts-wily xserver-xorg-lts-wily libgl1-mesa-glx-lts-wily libglapi-mesa-lts-wily libwayland-egl1-mesa-lts-wily libgl1-mesa-glx-lts-wily:i386 libglapi-mesa-lts-wily:i386
那个“官方”维基百科总是错误的。
xserver-xorg还要注意的是，如果你想要 4.2 内核，你不必升级。你可以只升级内核，方法是
sudo apt-get install linux-generic-lts-wily
答案2
首先，（这里要小心）删除有问题的软件包，然后运行安装：
sudo apt-get purge libgl1-mesa-glx libgl1-mesa-glx:i386 libglapi-mesa libgles2-mesa libglapi-mesa:i386 libgles2-mesa:i386
sudo apt-get install --install-recommends libgl1-mesa-glx-lts-wily libegl1-mesa-drivers-lts-wily libgles2-mesa-lts-wily linux-generic-lts-wily xserver-xorg-core-lts-wily xserver-xorg-lts-wily libgles1-mesa-lts-wily xserver-xorg-video-all-lts-wily xserver-xorg-input-all-lts-wily libwayland-egl1-mesa-lts-wily
如果您还需要 i386 版本，请也运行以下命令：
sudo apt-get install libgl1-mesa-glx-lts-wily:i386 libegl1-mesa-drivers-lts-wily:i386 libgles2-mesa-lts-wily:i386 linux-generic-lts-wily:i386 xserver-xorg-core-lts-wily:i386 xserver-xorg-lts-wily:i386 libgles1-mesa-lts-wily:i386 xserver-xorg-video-all-lts-wily:i386 xserver-xorg-input-all-lts-wily:i386 libwayland-egl1-mesa-lts-wily
或者不按照建议直接安装：
sudo apt-get install linux-generic-lts-wily xserver-xorg-core-lts-wily xserver-xorg-lts-wily xserver-xorg-video-all-lts-wily xserver-xorg-input-all-lts-wily libwayland-egl1-mesa-lts-wily
答案3
有同样的问题。通过先删除 libgles2-mesa-lts-utopic 和 libglapi-mesa-lts-utopic 解决：
sudo apt-get purge libgles2-mesa-lts-utopic libglapi-mesa-lts-utopic
然后按照wiki说明进行安装。
