CERBOT ContextualVersionConflict: (zope.interface 4.3.2 (/usr/lib/python3/dist-packages)

Question

I'm trying to get an SSL certificate using CERTBOT through " certbot-dns-route53 ". I've install certbot , aws-cli and c ertbot-dns-route53 plugin on Ubuntu 18.0

I fired the following command "certbot certonly --dns-route53 -d mydomain.com" and got the following error

    2021-04-24 13:05:20,028:DEBUG:certbot._internal.log:Exiting abnormally:

Answer 1

Try this in terminal:

> sudo apt remove certbot
> sudo snap remove certbot
> sudo pip uninstall certbot
> sudo pip3 uninstall certbot

then you run

> certbot

if ok you will get an error like:

> Command 'cerbot' not found, did you mean:

now, install certbot

> sudo apt install certbot

restart the terminal

Now, try if ok, run:

> certbot

if ok install certbot-dns-route53

> sudo apt install python3-certbot-dns-route53

Finally, restart the terminal and check to register your certificate.

This worked for me. ;)

Answer 2

Could be recent apt update conflicting files. Follow procedure below; which worked for me; Assuming Ubuntu >= 18.0

 sudo apt-get remove certbot
 sudo pip3 uninstall certbot
 sudo pip uninstall certbot

 ## Install snap if not installed
 sudo snap install core; sudo snap refresh core  
 sudo snap install --classic certbot

 ## check for any previous symlink and link again.
 whereis certbot
 sudo ln -s /snap/bin/certbot /usr/bin/certbot
 sudo ln -s /snap/bin/certbot /usr/local/bin/certbot
