Thank you for taking the time to report this bug and trying to help make Ubuntu better.
Please try using fuser -v to return the process locking process /var/cache/debconf/config.dat (if any). Kill the offending process and try performing the install again. More often than not this is only a transient situation and fuser will return nothing. Simply performing the update again should solve this issue. Please update this bug report if this resolves your issue.
