This failed all of a sudden. Anyone know how to circumvent it? Thanks.

Error: Nothing to do
Devtoolset-3 is end-of-life, and the community has not maintained all of its packages. Thus, there are some dependency bugs (Bug 1410152). As a work-around, you can point yum to the older Devtoolset-3 packages here instead, which do not have the dependency issues: https://copr.fedorainfracloud.org/coprs/rhscl/devtoolset-3/
Also, see the response here.
