Hello
I do try walk through course on learn.nvidia.com “Developing an Omniverse Kit-Based Application” (Course | NVIDIA) but do not work repo.bat commands
On bottom is log from terminal.

I need some help how to skip cloudfront.net verification. Or how to walk throught to work it.
I’m on corporate network with many connection restrictions.

I am afraid the kit-based apps require a good live connection to cloudfront.net. You will have to talk to your IT manager about allowing omniverse through your firewall. It is a well-known and trusted Amazon Server CDN. I don’t see why your network would be restricted from this.

Hello Richard,
we have proxy enabled and if we enter the path to the downloaded file in the browser it will download. The problem is when running scripts that don’t pick up proxy settings from system and environment variables. When downloading manually, we don’t know where to save the downloaded files so it doesn’t download them again. When I download and install the components elsewhere (outside the company environment) and copy the folders to their location on the corporate network, when I start it again it says it doesn’t have the correct versions and tries to connect to the repository.

Please where do I need to set the proxy for the scripts to work?
We tried setting variables with proxy directly in repo.bat and it didn’t work.
Or we need to know what it saves where so we can manually deliver files to it.

Hi Richard,
is there any solution how run kit-based apps using proxy. We are on enterprise and there is proxy very common. Is there some parameter like --proxy?

Hello,
we have the answer:

There are no proxy options.
To build an app in a secure environment, we can use a machine that packages that app (.\repo.bat package) for deployment.
Customers typically use a cloud instance to do this.

Thanks for the help.

That is correct yes

Yes about what? Is there no a solution for enterprise environment?
I have the simiular problem.
Package ‘repo_man’ at version ‘1.65.0’ is missing from local storage.

No that is not correct. Please download the latest KIT App Template for 106 and use the command mentioned above “repo package”. If it says “Package ‘repo_man’ at version ‘1.65.0’ is missing from local storage.” it means you have deleted the “packman-repo” folder before attempting to package. Download everything again.
