Sounds like a packaging mistake.  Both 3.8.1 and proj79 are stable so it is 
possible they just weren’t pushed to stable branch.

 

Probably best to report this to yum list -  
https://www.postgresql.org/list/pgsql-pkg-yum/

 

Which I have cc’d here.

Subject: [postgis-users] Dependencies for postgis25_12 not found (geos38, 
proj70)

 

I tried to install Postgres 12.2 with PostGIS 2.5 on Centos 7.7 today, but yum 
was unable to find the necessary dependencies for postgis25_12:

 

Error: Package: postgis25_12-client-2.5.4-1.rhel7.x86_64 (pgdg12)
           Requires: libproj.so.19()(64bit)
Error: Package: postgis25_12-2.5.4-1.rhel7.x86_64 (pgdg12)
           Requires: libproj.so.19()(64bit)
Error: Package: postgis25_12-2.5.4-1.rhel7.x86_64 (pgdg12)
           Requires: proj70 >= 7.0.0
Error: Package: postgis25_12-2.5.4-1.rhel7.x86_64 (pgdg12)
           Requires: geos38 >= 3.8.1
           Installed: geos38-3.8.0-1.rhel7.x86_64 (@pgdg10)
               geos38 = 3.8.0-1.rhel7
   

The required packages geos38 (3.8.1) and  proj70 (7.0.0) don't seem to be in 
either:

*       PostgreSQL Yum Repository
*       EPEL

Having hunted around, I finally found them in 
https://ftp.postgresql.org/pub/repos/yum/testing/common/redhat/rhel-7-x86_64/, 
however as I understand it, the packages in the "testing" repo should not be 
used in production (c.f. comment in .repo file).

 

Why do the postgis25_12 production packages have dependencies on packages that 
only seem to be available from a 'testing' repository?

 

Or should  geos38 (3.8.1) and  proj70 (7.0.0) be available from the production 
repositories?
