Errors on 8.04 upgrade page?

[Mario Vukelic]

Hi,

http://www.ubuntu.com/getubuntu/upgrading

For the upgrade Dapper -> Hardy, it recommends either "update-manager
-d" or "do-release-upgrade -d". However, in both cases the -d switch
checks for the next development release, which seems to me not to be
Hardy.

There just was a case on the -users list where this led to trouble:

Is this as bad as it looks and should this be filed as a bug?

Thanks
Mario
