Comment 3 for bug 518760

This happened to me just now, Thursday May 6, 2010, and this is not the test release. I'm using wubi.exe. After today's recommended upgrades to packages I had on Ubuntu 9.10, I noticed there was a link to upgrade to Ubuntu 10.04, so I clicked on it. Came back much later to see the error message described in this bug report. It looks like the fix either didn't work or wasn't applied to the wubi.exe upgrade from 9.10 to 10.04.
