My FreeBSD got an unknown fever today. When I updated my ports using portsnap, it gave the following error message:

#sudo portsnap fetch

Apparently, something in /var/db/portsnap/ is broken. Many people will try to remove /var/db/portsnap/ and run the command again. Do not do it. It will make portsnap failed. Instead, do the following:

sudo cp -r /var/db/portsnap /var/db/portsnap_backup
sudo rm -Rf /var/db/portsnap/tag /var/db/portsnap/files/*
sudo portsnap fetch extract
sudo portsnap update

Now your portsnap should be happy.
