What time is it?! Upgrade time!

That’s right, it’s that wonderful time of the year when Canonical releases the newest edition of Ubuntu. This time it’s Ubuntu 10.04 LTS*, codename Lucid Lynx.

There are lot’s of nice improvements made in the lastest release, some of them including:

  • Faster boot times
  • New Themes
  • Has social integration (Facebook, Twitter, etc…)
  • The UbuntuOne Music Store

I’ve always been a believer in keeping up with the latest and greatest. Every six months I’m watching and waiting for the newest release. I love it, it’s gives me a thrill. To be honest, the “problems” are fun for me too. I like the challenge of learning how to fix things, because I know that once I’ve fixed it, it stays fixed.

Something I do want to urge everyone to do. Check the integrity of your download. There’s nothing worse than downloading that brand new Operating System, burning it to a CD or DVD, installing it and having problems on initial boot-up.

Lets face the facts, downloading is not always perfect. With so many people downloading on release day, it’s no wonder I would need to check the integrity of my download. How do I check the integrity you ask? I’ll show you.

First open a terminal and go to the correct directory to check a downloaded iso file:

cd download_directory

Then run the following command from within the download directory:

md5sum ubuntu-10.04-desktop-amd64.iso
(md5sum ubuntu-10.04-desktop-i386.iso if you’re running a 32-bit Operating System)

md5sum should then print out a single line after calculating the hash:

3e0f72becd63cad79bf784ac2b34b448 ubuntu-10.04-desktop-amd64.iso


d044a2a0c8103fc3e5b7e18b0f7de1c8 ubuntu-10.04-desktop-i386.iso

Compare the hash (the alphanumeric string on left) that your machine calculated with the corresponding hash on the UbuntuHashes page.

An easy way to do this is to open the UbuntuHashes page in your browser, then copy the hash your machine calculated from the terminal into the “Find” box in your browser (in Firefox you can open the “Find” box by pressing <Ctrl> <F>).

When both hashes match exactly then the downloaded file is almost certainly intact. If the hashes do not match, then there was a problem with either the download or a problem with the server. You should download the file again from either the same mirror, or from a different mirror if you suspect a server error. If you continuously receive an erroneous file from a server, please be kind and notify the webmaster of that mirror so they can investigate the issue.**

Why should I check my .ISO’s integrity before burning to a CD or DVD? To put it simply… This might mean the difference between going to the Ubuntu Forum pissed and looking for help with a problem or going to the Ubuntu Forum proclaiming your love for 10.04. Integrity checks will never hurt you.

How can I get Ubuntu 10.04?
