Thanks for your feedback! I am new to RHEL (CentOS 7). Have been googling over the Internet to resolve the problem but so far still struggling. I have installed PostgreSQL already and now trying to install PostGIS. I see that EPEL already contains GEOS package and I don't need EL GIS repo. Based on your comment, do you suggest to remove repositories which are not required? Why I messed up with so many unwanted repositories because when I tried to install PostGIS using this link: http://www.postgresonline.com/journal/archives/362-An-almost-idiots-guide-to-install-PostgreSQL-9.5,-PostGIS-2.2-and-pgRouting-2.1.0-with-Yum.html#PostGIS I ran into problems, then somehow I used other links of PostgreSQL 9.4 which was not realistic somehow. _______________________________________________ epel-devel mailing list -- epel-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to epel-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
