I upgraded to 8.04 on AMD64 machine. I started to upgrade to 10.04 LTS using the System -> Admin -> Update manager. After packages started installing began getting MANY error popup windows saying dpkg exiting with errors. Looking at the terminal window I see a lot of "cannot utime" and it appears to be some error with tar. I saw on another forum that Lucid has a bug with tar. Now the distribution upgrade has just locked. What should I do?
