Either these are different file systems, or this file system doesn't support hardlinks, or these directories don't exist, or there is a permissions problem, or the file system is out of inodes or full. Use df, df -i, and ls -ld to check each of these possibilities. Quitting...

Confirmed.

Run the following commands:

  sudo apt-get install backuppc
  sudo apt-get remove backuppc
  sudo apt-get install backuppc

Consistently reproduces this issue.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as 'Triaged' and let them handle it from here. Thanks for taking the time to make Ubuntu better!

It is a permissions problem. The quick manual fix for this is to change the user and group of the files /var/lib/backuppc/pc and /var/lib/backuppc/cpool to 'backuppc'. I'm working on a packaging fix.
