perfSONAR User Q&A and Other Discussion

["David J. Chaffin" <>]

Jason, 

At least some of postgresql 9.5.21-1 has been installed from the pgdg95 repo  (the postgresql95 site). That's a newer version so yum won't auto upgrade to the perfsonar verson.

Error: Package: postgresql95-contrib-9.5.3-2PGDG.rhel7.x86_64 (perfSONAR)

           Requires: postgresql95-libs(x86-64) = 9.5.3-2PGDG.rhel7

           Installed: postgresql95-libs-9.5.21-1PGDG.rhel7.x86_64 (@pgdg95)

You will want all the postgresql95 rpms to be from pS, do a yum list all and grep for pgdg95 and do a yum downgrade on all of them, or get the pS rpms with yumdownloader and do an rpm force install.

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