place the iso in your home directory, then open a terminal with Ctrl+Alt+T, or by selecting the "terminal" application from the program launcher

Now type "md5 *.iso"

this will give you the MD5 -- check that the output matches the posted output for the MD5s here:

I just asked Google, and got help immediately.
Now I try to install X-CD-Roast, to burn *.iso,
and check MD5Sum according to the answer got from Google.
It's good to have more info and more "medicines" for problems.

just for the record, the links I posted are https, and are directly owned by canonical. This is more secure than requesting a hash from google, as you will not know where google got that hash from, or (unless you use secure google), that your communications have not been altered anywhere on the packet relay route between google and your system.
