How do I upgrade my Ubuntu 10.04 LTS to 12.04 LTS?

Question

How do I upgrade my Ubuntu 10.04 LTS to 12.04 LTS? My update manager tells me my Ubuntu release is not supported anymore.

I did pressed Alt+F2 and typed update-manager-d but still had no luck. I could really use some help with this issue. Thanks in advance!

Why would you want to upgrade to 12.04 LTS instead of 16.04 LTS? — terdon, Sep 19 '16 at 17:41
IMHO, upgrades are not an option here. You need to backup and reinstall. Ubuntu 12.04 only has 7 months of support left to it, which makes 14.04 or 16.04 better options. — mikewhatever, Sep 19 '16 at 17:47
How to install software or upgrade from an old unsupported release? -- not a dupe yet until you make up your mind whether to upgrade to 12.04, 16.04 or do a fresh (re)install of 16.04 (better option). — karel, Sep 19 '16 at 17:48
When I read the help guide, it said I could not skip. I have to go from a 10.04 LTS to a 12.04 LTS until I reach the newest version. If I misunderstood, please tell me the correct way. — Z. Newt, Sep 19 '16 at 23:50
@Anwar: Yes it should. The target upgrade release 12.04 is still supported so that should be no problem either. — David Foerster, Sep 20 '16 at 11:07
Is your machine dual booted with windows or just ubuntu based? — minigeek, Sep 20 '16 at 11:44

Step 2 will fail because the package repositories for 10.04 are offline and were moved to old-releases.ubuntu.com. – David Foerster Sep 20 '16 at 11:10
