启动时出现问题：启动版本 219

安装 Ubuntu 15.04 后，启动系统时出现消息，提示启动时间较长。如果有人能帮忙，我将不胜感激。

补充：

已经测试过命令：

sudo systemctl enable lightdm.service -f

并得到以下结果：

Synchronizing state for lightdm.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d lightdm defaults
Executing /usr/sbin/update-rc.d lightdm enable
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.

Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).

问题仍然存在。如果你能帮助我，我将不胜感激。

我不知道为什么会发生这种情况，并且我还检查了我的fstabUUIDblkid 是否正确，因此我使用这个脚本将我的内核升级到 4.0.1 稳定版：

对于 32 位：

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-headers-4.0.1-040001_4.0.1-040001.201505081133_all.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-headers-4.0.1-040001-generic_4.0.1-040001.201505081133_i386.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-image-4.0.1-040001-generic_4.0.1-040001.201505081133_i386.deb

对于 64 位：

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-headers-4.0.1-040001_4.0.1-040001.201505081133_all.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-headers-4.0.1-040001-generic_4.0.1-040001.201505081133_amd64.deb

$ wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.1-wily/linux-image-4.0.1-040001-generic_4.0.1-040001.201505081133_amd64.deb

下载后，通过

sudo dpkg -i linux-headers-4.0.1*.deb linux-image-4.0.1*.deb

并重新启动

sudo reboot

https://github.com/tavallaie/upgrade-kernel-4.0.1 * github 上的这个脚本目前只适用于 64 位操作系统。
