I tried to run the Hardy upgrade, and it finished fetching files and installing them, but then said that due to an error it would not proceed with the upgrade and that my computer would be restored back to the way it was. But upon restart the computer I was running hardy with no apparent problems until today when updat manager and apt-get both give me this error:
Reading package lists... Error!
E: Problem parsing dependency Depends
E: Error occurred while processing libsasl2-modules-gssapi-mit (NewVersion1)
E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_hardy_universe_ binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
How can I fix this?
