Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

The problem can be corrected by updating your system to the following package versions:

Ubuntu Release	Package Version
14.04 trusty	linux-image-3.13.0-201-generic – 3.13.0-201.252
	linux-image-3.13.0-201-lowlatency – 3.13.0-201.252
	linux-image-generic – 3.13.0.201.211
	linux-image-generic-lts-trusty – 3.13.0.201.211
	linux-image-lowlatency – 3.13.0.201.211
	linux-image-server – 3.13.0.201.211
	linux-image-virtual – 3.13.0.201.211
