Would binaries built on centos:6 work fine on Ubuntu-16.04?

Generally yes.

The main issue with Linux compatibility is ensuring that software is built on a system with a version of glibc that is compatible. In practice this mean the glibc version used to build the software sets a lower limit on the allowed version of glibc. CentOS 6 provides glibc 2.12, which is one of the older versions of glibc around (hence why it is used). Ubuntu 16.04 provides glibc 2.23. So anything built here should work fine in terms of glibc requirements.

There are other things that get linked in like libstdc++. However we build with an ancient copy of gcc. So in practice our requirements on this front are minimal enough to be satisfied by the OS. There are some trick when building software with different versions of gcc (e.g. 4 vs. 5), but the underlying libstdc++ library is backwards compatible. So it shouldn't result in any issues running our packages.

That said, it is possible if you are relying on things from yum that there could be a discrepancy between systems. Though I don't know of any reports about this causing issues in practice. In the long run, it looks like we will be wrapping up yum packages for use with conda to avoid even this potential issue.
