I'm trying to install certbot on Amazon Linux. The following command results in a bunch of errors:

Installing Certbot on the Amazon Linux AMIs is a bit tricky.

Amazon themselves publish some information about it here: [https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html#letsencrypt](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html#letsencrypt)

Do you still get the packaging problems while following that guide?

Edit: I just tried out those instructions on a fresh instance, and they indeed are broken 😕 . @schoen does anyone need to be tagged about it?

Darn, that’s unfortunate. Do you know how quickly this can be fixed? Some of the customers of my website are complaining about their browser throwing warnings at them about the safety of the website.

You can try install it directly from pip as shown in this comment: [https://github.com/certbot/certbot/issues/1680#issuecomment-358728515](https://github.com/certbot/certbot/issues/1680#issuecomment-358728515)

Otherwise, I’d suggest trying a different client with less complicated dependencies, such as acme.sh or acmetool or anything from [https://letsencrypt.org/docs/client-options/](https://letsencrypt.org/docs/client-options/)
