The new Ubuntu release 8.04 Hardy Heron will be released tomorrow.

If you can’t wait, upgrade to the release candidate, available now, and then upgrade to the final version again tomorrow. Note that its not recommendable to install the release candidate on working machines but what the heck, you only live once. It was released just a few days ago and so many bugs can not have been solved since then, could it?

To upgrade Hardy Heron release candidate:

Alt+F2
Enter following command: upgrade manager -d
Click on upgrade to 8.04 lts and follow the instructions.

Tomorrow after the release you can upgrade again doing following:
Alt+F2
Enter following command: upgrade manager -c
Click on upgrade to 8.04 lts and follow the instructions.
