First attempt of installing it, I got the error. But after some research I found out that the default repository indicated in /opt/bahmni-installer/bahmni-playbooks/group_vars/local, is no longer available. You just have to open the file “local” in /opt/bahmni-installer/bahmni-playbooks/group_vars and edit the value of these:
- postgres_repo_rpm_name:
- postgres_repo_download_url:
the value in default of that is no longer available so you have to change it to this:
- postgres_repo_rpm_name: pgdg-redhat-repo-latest.noarch.rpm
- postgres_repo_download_url: https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/
After making the changes I rerun the installation and postgresql successfully installed.
