It was not.

Here is the solution to stop errors like: fail2ban.server : ERROR Unexpected communication error on ubuntu 9.04 with Fail2ban from the repo's. First we need to install python2.5 because Ubuntu 9.04 has 2.6: sudo apt-get install python2.5 Confirm with Y where needed. Now, we need to edit the fail2ban binary so that it makes use of python2.5: sudo gedit /usr/bin/fail2ban-server Change the first line ( _#!/usr/bin/python_ ) to the following: #!/usr/bin/python2.5 Save and close the file. Now restart the fail2ban service. Note: sudo /etc/init.d/fail2ban restart did not work for me, so I did the following: sudo /etc/init.d/fail2ban stop sudo /etc/init.d/fail2ban start And If you check the log files now ( **vim /var/log/fail2ban.log** ) you will not see the error anymore.
