 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

i have tried installing yum-utils and package-cleanup --leaves but still the following error shows up. Can anyone tell me how to prevent this issue? thanks. btw my servers os-release

NAME="Amazon Linux AMI"
VERSION="2018.03"
ID="amzn"
ID_LIKE="rhel fedora"
VERSION_ID="2018.03"
PRETTY_NAME="Amazon Linux AMI 2018.03"
ANSI_COLOR="0;33"
CPE_NAME="cpe:/o:amazon:linux:2018.03:ga"
HOME_URL="http://aws.amazon.com/amazon-linux-ami/"

Can anyone help me with this? I think if I could remove all these dependencies issues than I could install the python2-certbot-nginx and i could do ssl. Any help can i get? Thanks in advance.
