I want to update my Ubuntu 14.04 system from the terminal and I know that
sudo apt-get update && sudo apt-get upgrade are the commands but when I check the update manager kernel updates are still there. Why? and what can I do to update the kernel from terminal.
You need to perform
dist-upgrade inorder to install/remove all dependencies related to the packages upgraded using
upgrade . From the manual page of apt-get .
dist-upgrade dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism for overriding the general settings for individual packages.
The better way would be to upgrade
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
However, be careful while using
dist-upgrade as it might also remove packages to satisfy dependencies.
