Hi! libunwind package is now part of RHEL 7.2. It got retired from EPEL7 three days ago (and incidentally the Release went backwards so upgrade path is broken): https://bugzilla.redhat.com/show_bug.cgi?id=1288313 Unfortunately, that leaves CentOS users in a bit of a pickle, as libunwind is no longer installable (unless they enable CR repository or wait X weeks until CentOS 7.2 is released). NGINX depends on gperftools which depends on libunwind. So NGINX cannot be installed on CentOS: https://bugzilla.redhat.com/show_bug.cgi?id=1289073 I could rebuild NGINX without gperftools as a temporary solution, but that would break NGINX for anyone using the google perftools module. If I don't rebuild, then users can't even install NGINX in the first place. It seems I'm in between a rock and a hard place. By the way, I don't actually plan on rebuilding NGINX without gperftools as that would break it for existing users, and new users can enable CR (but that assumes the user can figure out the solution themselves). So, in the general case of packages being retired from EPEL7 because they have moved to RHEL, how do we avoid missing packages in the future?
