Error: role "posgres" already exists in fresh Centos Minimal installation.

@sanjayap

Can you please give more details, on steps you did. The above is usually a warning. Give it some time, the install is still in progress.

Installing through https://bahmni.atlassian.net/wiki/display/BAH/Install+Bahmni+on+CentOS procedure and its the fresh installation.

Did you manage to install Bahmni?

@gsluthra

last error shown and stopped the installation as shown screenshot

The script could not read the Bahmni version environment variable. If you see the wiki documentation it asks you to set the environment variable on the command line before invoking the install command. Can you please set the environment variable and rerun the command.

export BAHMNI_VERSION=0.78
