Un attended distro upgrade in Ubuntu
We use Ubuntu as this is one of the greatest Linux distro. In every 6 months Ubuntu is upgraded. The problem with up-gradation of Ubuntu is that it takes a lots of time and it is interactive. That is you have to be there to answer some question at the time of up-gradation. This is really painful. So if you decided to do the up-gradation overnight, this is not possible. But fortunately there is a way you can do this in no-interactive way. You can use following command. do-release-upgrade -d -f DistUpgradeViewNonInteractive But be careful that it will always go to the default setting. If you want to change some setting from it's default to some another one you can do that using sudo dpkg-reconfigure . cheers A . Paul
