Upgrade 18.03 to 19.1x (pelican-stretch)

Hello,
I paste the commands that will allow you to do a Recovery with the root user :

wazo-service stop
dpkg --purge --force-all wazo-auth
rm -r ~/.config/wazo-auth-cli
sudo -u postgres psql -d asterisk -c “DELETE FROM public.auth_user WHERE username = ‘wazo-auth-cli’;”
apt-get install wazo-auth

### Verification of writing in the database ###

sudo -u postgres psql -d asterisk -c “SELECT * FROM public.auth_user WHERE username = ‘wazo-auth-cli’;” -o “/tmp/auth_user_wazo-auth-cli.txt”

!!! I advise you to test this on a VM, or a few things that will allow you to restore everything, in case of malfunction. !!!
