Using a EDGE for update is really not cool but i have to. So my update always runs in night when i go to sleep.

Is there any way to set ubuntu to auto-shutdown after completion of update.

Note: I saw a link in a similar post that redirects to a python script(SEE HERE) but i am not well acquainted with these kind of scripts.

Any help would be appreciated.

  • The python script you refer to seems fairly harmless.

Technically you could do everything in the shell.

Just type

sudo -i
apt-get update && apt-get -y dist-upgrade && shutdown -P now

sudo -i makes you root till you manually log out of it by using exit this is just to make sure that your sudo rights don't time-out if the update takes too long (usually sudo rights time out after 15 minutes if I remember correctly).
The && operator concatenates the commands. Basically you can read it as:
If command 1 finished succesfully execute command 2, if command 2 finished succesfully execute command 3
and so on...Note: The other commands will only run if the command before it finished succesfully.

The -y parameter after apt-get answers all prompted questions with 'yes'.
The shutdown -P now shuts your computer down for power-off(-P) immediately (now).
To get an overview what other parameters there are for shutdown run shutdown --help

  • Thanks @Daniel but the weird thing i have seen in updating through terminal is it leaves few updates without installing them. And why dist-upgrade? Jun 6, 2013 at 11:36

    apt-get upgrade sometimes leaves out some upgrades, notably kernel upgrades. apt-get dist-upgrade will however upgrade the kernel, and could remove some packages that upgrade would usually not. Visit man apt-get for more info, or this question.

  • like Alaa said 'apt-get dist-upgrade' upgrades all the packages that would be held back by 'apt-get update'

  • Won't it upgrade to the latest ubuntu release available at time. Jun 6, 2013 at 13:58

    No it will not do that. update only updates packages to their new versions. dist-upgrade is able to also install new dependencies and uninstall obsolete ones. So update will hold back any update that would require to install new dependencies
