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-3.13.0-202-generic –  3.13.0-202.253  
linux-image-3.13.0-202-lowlatency –  3.13.0-202.253  
linux-image-generic –  3.13.0.202.212  
linux-image-generic-lts-trusty –  3.13.0.202.212  
linux-image-lowlatency –  3.13.0.202.212  
linux-image-server –  3.13.0.202.212  
linux-image-virtual –  3.13.0.202.212
