As of the time of writing, you may get an error like this when installing openssl inside a docker container with CentOS image:
Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. (...)
You can fix this by enabling CentOSPlus repo in your Dockerfile with:
sed -i '/^\[centosplus\]$/,/^\[/ s/^enabled=0$/enabled=1/' /etc/yum.repos.d/CentOS-Base.repo
Then do a regular
yum install openssl-devel and it should work!
NOTE: Get rid of the
RUN if you are not in a Dockerfile but in a shell script or session.
