We have Karmic Koala on our workstation.

When we tried upgrading using Update Manager, the window froze (turned black and white) and we had to "Force Quit".

We used the command-line "sudo do-release-upgrade -d", it shows "Checking new ubuntu release" without any further output.

Both methods did not work for about 2-3 hrs. Should we have tried longer? If not, how do we proceed now? Thank you.


Ubuntu 9.10 (Koala) is no longer supported, and so upgrading from 9.10 to 10.04 LTS is also not supported.

Once you have your data and settings backed-up, you should do a fresh install of Ubuntu on your workstation. There may be initial issues with drivers, but this should mostly be resolved by doing an update.

Once you have 10.04 LTS working, then try out (but do not immediately install) Ubuntu 12.04 LTS. This may also work on your PC, but may not be quite as fast.

I have successfully run both 10.04 LTS and 12.04 LTS on an HP Mini netbook (Atom processor, 1GB RAM) or ex-corporate desktops (P4 2.8GHz, 1GB RAM).


Any attempt to upgrade is potentially a high risk to any data (and settings) on the PC. Therefore, the data (and settings) must first be backed-up.

As you have already identified issues with attempting to upgrade, it seemed better advice to suggest that you instead do a new install.

Note: Any inconvenience to yourself and other users also needs to be weighed against the potential loss of data, and likely failure, of the upgrade attempt.

  • +1, 9.10 (Koala) is no longer supported, and so upgrading from 9.10 to 12.04 LTS is also not supported. I wasn't aware that unsupported versions are not upgradable. – Ankit Nov 23 '12 at 8:44
  • The issue being that any upgrade problems may directly relate to behavior of the unsupported platform you are updating from. The upgrade can be attempted, but lacks 'support'. – david6 Nov 23 '12 at 8:48
  • Thank you. But we do not want a fresh installation, since we have large amount of data and user accounts on our workstation as we are not the only ones using it. A fresh installation might jeopardize their data too. Is there any other way? – Chinnu Nov 23 '12 at 9:23
  • We are thinking of using clonezilla for backup. We are using it for the first time.Does the softare include backup for settings like userids etc. too – Chinnu Nov 23 '12 at 10:32
