@SwartzCr, could you look into this?
@paddif, there are other clients that have significantly fewer dependencies, like acme.sh.
If you can't get Certbot to work, you might be able to use one of the other clients. However, it won't interoperate with Certbot in the sense of making use of your existing certificate configuration or saving new certificates in the same place. So you would also have to deal with some web server reconfiguration.
