1 Backup the home directory while you are logged in:
  sudo cp -rp /home/user /home/user.backup
  [Check that your home backup has everything!!!]

2 switch to using root (another user account with sudo privileges would work equally well).

3 Delete your home directory rm -rf /home/user

4 Before removing the packages ecryptfs-utils and libecryptfs0 would work, I needed to remove /home/.ecryptfs/<myusername>. (It complained that ecryptfs-utils was in use.)

5 Remove the packages apt-get remove ecryptfs-utils libecryptfs0

6 Restore your home directory mv /home/user.backup /home/user

7 reboot

8 Remove any of those .Private .ecryptfs folders rm -rf ~/.Private rm -rf ~/.ecryptfs
