When I update my Ubuntun 9.10 to 10.04 from the iso file, and run the command "sudo gksu "sh /cdrom/cdromupdate"", it reminds me that "Authentication failed". Before the warning, the updating box stops at "calculating the changes" for a very long time...

I don't know how to deal with it. Any help?
Thanks!

I just tried to update the system online by updating the sources.list to Lucid's sources. It also warns that "Authentication failed"...
