I have installed Ubuntu 12.04 LTS two weeks ago by downloading the iso image, creating a startup usb stick from this image, booting the live system and finally installing. I have been working successfully during these two weeks in order to get everything I need up and running. :-)

Since most of the software needed is properly working I decided to tell the update-manager to look for packages to update. After downloading the package information the update-manager says (1) "The software on this computer is up to date. The package information was just updated". However, immediately after this, a second dialog pops up and says (2) "Not all updates can be installed. Run a partial upgrade, to install as many updates as possible". If the software is up to date, there should be nothing to install, so (2) contradicts (1).

Choosing the offered "Partial Upgrade" results in (3) "Upgrading over remote connection not supported. You are running the upgrade over a remote ssh connection with a frontend that does not support this. Please try a text mode upgrade with 'do-release-upgrade'." Finally, launching do-release-upgrade on the console (e.g. Ctrl-Alt-F5) reports (4) "Checking for a new Ubuntu release. No new release found." Since (4) supports (1), it does not matter if upgrading by means of a remote connection is supported (3).

Please give me a hint how to get the update-manager properly working. I can't tell, if my installation is complete and up to date or if there are package updates available, I should install but my package management has an aching stomach.

Kind regards,


  • Thank you for your replies. Problem solved. Bummer, that I didn't come up myself with doing apt-get update, apt-get upgrade and apt-get dist-upgrade. :-( Somehow, the package management had tangeld up. Best wishes, Berket – Berket Tuncer Khemal Jan 4 '13 at 6:37

To try to solve your problem, open a terminal (Ctrl+Alt+T) and enter the following two commands, one at a time, in order. The first command will ask for your password. The second command may take a little while if you have not managed to update since installing.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

When complete, close the terminal and restart your machine. Try Update Manager again.

  • Change the first line to: sudo apt-get update && sudo apt-get upgrade. You need to complete upgrade and dist-upgrade to be fully latest code. – david6 Jan 3 '13 at 21:12

    @david6 - thanks, I've made the change. I'm not sure that you are correct, though, because I have never needed to do an upgrade before a dist-upgrade. – Paddy Landau Jan 4 '13 at 13:16
  • The first two provide all updates, whereas the last also provides any new applications or major updates (that change features). You could operate 12.04 LTS without step 3 for a lengthy period, with no loss of security or functionality. That said, step 3 is an optional step, that should only be used after you have completed the first two. Which is also why the first two are usually shown as a single line. – david6 Jan 4 '13 at 21:19
