Hi,

on last update we got some errors updating postgis in RHEL8:

Problem 1: cannot install the best update candidate for package postgis31_13-3.1.12-10PGDG.rhel8.x86_64
- nothing provides libpcre2-8-0 needed by postgis31_13-3.1.12-13PGDG.rhel8.x86_64 from PostgreSQL_PostgreSQL13_-_RHEL_8_x86_64
Problem 2: cannot install the best update candidate for package postgis31_14-3.1.12-10PGDG.rhel8.x86_64
- nothing provides libpcre2-8-0 needed by postgis31_14-3.1.12-13PGDG.rhel8.x86_64 from PostgreSQL_PostgreSQL14_-_RHEL_8_x86_64

I've found that the dependencies changed from pcre to libpcre2-8-0:

$ rpm -qp /tmp/postgis31_13-3.1.12-13PGDG.rhel8.x86_64.rpm --requires | grep pcre
libpcre.so.1()(64bit)
libpcre2-8-0
$ rpm -qp /tmp/postgis31_13-3.1.12-10PGDG.rhel8.x86_64.rpm --requires | grep pcre
libpcre.so.1()(64bit)
pcre

The libraries libpcre2 are provided by pcre2 on RHEL8+9:

$ rpm -qf /usr/lib64/libpcre2-8.so.0
pcre2-10.32-3.el8_6.x86_64
$ rpm -qf /usr/lib64/libpcre.so.1
pcre-8.42-6.el8.x86_64

I've found the commit for postgis 3.1: https://git.postgresql.org/gitweb/?p=pgrpms.git;a=commitdiff;h=a2e39ff2a23b5c925ff0fb08340c6a7f85313...
As I can see you use pcre2 only from RHEL10 upwards, but RHEL8 and RHEL9 also provides the library with package pcre2 .

Thanks and Regards,

Christopher Lorenz

Thanks for the report!

That is right. Pushed fixes to git repository and also building the RPMs
now. I'll push them along with tomorrow's minor release updates.
