Ok, I think I learned how to do this:
I first uninstalled certbot using the following commands:
sudo apt-get purge certbotapt
sudo apt-get purge python-certbot-apache -t jessie-backports
sudo apt-get purge apache2
then I manually deleted the files / folders in the following:
- / myuser / certbot-auto
- /myuser/.local/share/letsencrypt/
- /etc. / letsencrypt /
- / var / Library / letsencrypt /
- / var / Magazine / letsencrypt /
then I installed a new fresh instance of apache2:
sudo apt-get install apache2
sudo service apache2 restart
Now everything has returned to where I was, and I can work on setting a personal / local ssl for my project.
Hope this helps you too;)
