I recently decided to install Plone to test its' usefulness as a content management system. When installing Plone on Debian Lenny, I ran into the following error:
pycentral: pycentral pkginstall: not overwriting local files
After a quick search, I found an easy way to resolve the error is to run the following command:
echo "overwrite-local = 1" >> /etc/python/debian_config
Then just install Plone as you normally would, and remove the added line from /etc/python/debian_config after the installation completes:
apt-get install plone3-site
