Thank you for taking the time to file a bug report.

From the logs it looks like there is a missing file. Can you try running
'sudo apt-get install -f' to see if it now completes, otherwise you may
need to reinstall apache.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we would
be grateful if you would provide a more complete description of the problem
with steps to reproduce, explain why you believe this is a bug in Ubuntu
rather than a problem specific to your system, and then change the bug
status back to "New".

For local configuration issues, you can find assistance here:
