@bmw Thanks for this. FYI, after removing python2-boto3 and attempting to install python-boto3 instead, YUM still ends up installing the former:
---> Package python2-boto3.noarch 0:1.4.6-1.el7 will be installed
I am using most recent RHEL 7 release:
Operating System: Red Hat Enterprise Linux Server 7.6 (Maipo)
Anyway, the naming is quite confusing and maybe it is also good idea to change all certbot packages at some point to new convention python2-certbot-* => python-certbot-*?
