while updating software on Ubuntu 14.02 LTS using Software Updater, I am having problem.
There is 62.6 MB of update available, but after opening the Software Updater window, it shows all updates checked except one
User space IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator
check box for this update is grayed out and unable to select this update to download.
After clicking Install Now leaving that update unchecked, it gives error just after.
I have also tried the command line
$sudo apt-get update
$sudo apt-get upgrade
But nothing happend.
