Comment 4 for bug 734645

Thank you for taking the time to report this bug and helping to make Ubuntu better.

9.04 to 10.04 is not a normal upgrade path; you should normally step through 9.10 (as described here: https://help.ubuntu.com/community/UpgradeNotes).

Please could you try running the following commands in a terminal to see if this resolves the issue:

  sudo dpkg-reconfigure openssh-client
  sudo apt-get -f install

Please update this bug report if this does resolve the problem.
