i just download i386-desktop , amd64-desktop , and i386-server.
at the MD5SUMS check the i386-desktop turned
amd64-desktop and i386-desktop are just fine.
i am going to install amd64-desktop now to come with results..
Re: wrong MD5SUMS
If the md5sum is wrong, it's because your download went bad. Nothing else
Please, test it, and tell us what is your experience!
It would be fine that you report your results in the Launchpad iso tracker, as you can read in the Henrik's PostIt
