First run
|
1 2 3 |
# type certbot certbot is hashed (/usr/bin/certbot) |
To find out where certbot is installed to. Or command -v certbot if you prefer.
Then run head /usr/bin/certbot and note what version of Python it’s using:
|
1 2 |
#!/usr/bin/python3 |
In my case, it was using Python 3.
I noticed from my pip output it was trying to install a Python 2.7 package:
|
1 2 3 |
# pip install certbot-dns-digitalocean Requirement already satisfied: certbot-dns-digitalocean in /usr/local/lib/python2.7/dist-packages |
So how do we get pip to install Python 3 packages instead? Just copy the instructions from here:
|
1 2 3 4 5 |
cd /tmp curl -O https://bootstrap.pypa.io/get-pip.py python3 get-pip.py rm get-pip.py |
Now you should have the pip3 command, so run this instead:
|
1 2 |
pip3 install certbot-dns-digitalocean |
And now try again:
|
1 2 3 4 5 6 7 8 9 10 |
