Fix: dpkg: error: cannot remove architecture X currently in use by the database
# You try:
sudo dpkg --remove-architecture armhf
# and get:
# dpkg: error: cannot remove architecture 'armhf' currently in use by the database
# So you have to remove the armhf packages installed to be able to `dpkg --remove-architecture armhf`
apt-get remove --purge `dpkg --get-selections | grep armhf | awk '{print $1}'`
# Then:
sudo dpkg --remove-architecture armhf
# SUCCESS!!!
