Creating a system role breaks all member inheritance rights.
Example: if a user does not see any roles or is missing a role in K2 Management > Users > Roles:
In this case the Package and Deployment role, the following error will be displayed to the user:
All members / users that were in the system role will lose their rights to create a new package for deployment:
If there are no roles in management, confirm that the role exists in the K2 Database first:
If the roles exist this will indicate that a user with rights might have attempted to create the role again.
Contact K2 support for assistance as the current resolution is to restore a K2 database backup.
