So I have Ubuntu installed on my pc, and I want to upgrade to the new Ubuntu which was just released. When I check for any new updates it doesn't show any upgrades to the new release. How can I fix this? Thanks!
If you're not getting an option to upgrade then your local mirror might be out of date, you can either wait a bit for that to resolve itself, or manually switch to another mirror. You should also make sure your software properties settings are correct.
After that follow the upgrade instructions:
do-release-upgrade in terminal should work
Press Alt + F2 and paste:
Then go to tab "Updates" and at "Notify me about new Ubuntu version" choose "For any version".
(Or if you are at 10.04, go to tab "Updates" and at "Release upgrade" choose "Normal Releases")
Finally open Update Manager and check it again.
In the Update Manager settings, make sure "Notify me of a new Ubuntu version" is not set to "Never."
You can select any of the Normal or LTS releases in the Release update setting. After exit, reload.
You can then start update manager and click check.
One property of Ubuntu is unless you update all the packages to a desired version for the upgrade, option to upgrade will not appear.
so first, kindly apply all the updates of all the packages. Then when you click update, this option of 12.04 should appear.
12.04 is a "Long-term support" version. By default it will only offer upgrades to the next LTS in a few years time.
To force it to offer upgrading to a normal release such as 12.10 you can open Software sources and set Show new distribution releases to Normal releases.

12.01 is less then 12.04. Meaning it's not an update. I assume you mean 12.10. Please update your question if that is the case.
12.04 is a LTS release. By default it only updates to the next LTS release (13.something a long time from now) You can change this by running
update-manager from the terminal and clicking settings. On the "Updates" tab select Notify me "For any new version". Then close the window.
update-manager again and you should get a little popup for the upgrade.
Make sure this is what you want to do though. For most casual users, 12.04 is recommended (and is the latest).
