That’s it! you’ve successfully upgraded to Ubuntu 14.04 from Ubuntu 13.10. The above upgrade instructions was written for Ubuntu, but you can also use these instructions to upgrade any Ubuntu based distributions such as Xubuntu, Kubuntu or Lubuntu 14.04.
Release notes show up blank for some reason. I press ‘Upgrade’ and it does nothing. Anyone have an idea why?
I upgraded from 13.10 to 14.04, After reboot, system got stuck after
1. starting apache2 webserver and
2. Applying battery power settings
even networking is disabled. Not able to connect with internet even with Lan wire. What Should I do ( I have taken backup by logging into terminal tty1).
According to the Ubuntu documentation, if you use update-manager -d you get the devel-release what has the next warning:
‘Development releases often suffer from package breakages and other problems. Only install a development release if you are prepared to attempt to fix these problems for yourself.’
In order to upgrade from 13.10 to 14.04 in my case using Xubuntu it is best to just enable, check for all distro updates and follow the normal procedure to check if any update is required as detailed in the documentation
This will lead you to the LTS release for normal use, not the development release
Good point Raul!!
We have also mentioned in post that “-d” will check for development release :).
“Step 2: After your system got updated. Press “Alt+F2“ and type ”update-manager -d”. Here, “-d” is for checking development release. This will launch the software updater.”
Thanks!!
