Comment 2 for bug 671317

I solved it. All you need to do is to go to terminal and type in "sudo gedit /var/lib/dpkg/status" (w/o the quotes), now before we go ahead and troubleshoot this issue, I would like to tell you that this error was intermittent because of incomplete installation. Look at this error message "pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate file for the sun-java6-jre package. This might mean you need to manually fix this package."

So after you have typed in sudo gedit /var/lib/dpkg/status on terminal with root privileges, you will see a gedit (or any default text editor you have got), find the part where it's got " sun-java6-jre", you will notice that installation status is "incomplete", now delete the whole part, save the file and quit terminal. You can have aptdaemon up and running as usual!!
