[postgis-users] How to install the latest PostGIS (3.0 or very latest) on CentOS 8.1?

[Regina Obe]

Devrim,

Thanks for the instructions, I added to this page -
https://postgis.net/install/

> so therefore, is there anything in that section that I need to do?

I ran into a stumbling block on a fresh Centos 8.1

dnf -y config-manager --set-enabled PowerTools 

Gave -  "No such command: config-manager. Please use /usr/bin/dnf --help"

I had to do this beforehand -- can you add this line to the instructions
after the epel-release install.

yum install dnf-plugins-core

#It installed okay after, but when I go to do a yum update I get this error

yum update

use not only best candidate packages)


yum update --nobest

#any rate seems to have installed okay, but I assume the above will cause
issues for upgrades
