We get this error when trying to submit from linux command line:
Deadline Command 8.0 [v8.0.0.69 Release (f4bf23642)]
Configuration Error: The specified repository path (/mnt/isila/deadline/repository8) does not contain the necessary database connection settings file.
There may be a network issue, or a valid repository has not been installed at this location. If one has not yet setup a repository, it is possible to do so using the repository installer included in the installation files.
We got this on old builds of the windows version, due to the xml file having been replaced by the ini file.
