Hi Aleksander,
When I have seen this error in the past, it has been due to an issue with how the resource bridge was deployed. Below are the steps I would use to resolve this:
- Fully clean up the current environment using the steps here - https://learn.microsoft.com/en-us/azure-stack/hci/manage/uninstall-arc-resource-bridge
- Redeploy Arc VM management using the command line steps here - https://learn.microsoft.com/en-us/azure-stack/hci/manage/deploy-arc-resource-bridge-using-command-line?tabs=for-static-ip-address-1%2Cfor-static-ip-address-2. Ensure that you check/confirm your environment variables are all correct and that you choose the correct steps for either static or DHCP.
- As the image above indicates you are using an Ubuntu image, ensure that the image was properly prepped using the steps here - https://learn.microsoft.com/en-us/azure-stack/hci/manage/virtual-machine-image-linux-sysprep. There are links in the left column of the above link that document how to create additional images.
- Finally create your virtual network using the steps here - https://learn.microsoft.com/en-us/azure-stack/hci/manage/create-virtual-networks
Once these steps are completed, you should be able to deploy your images successfully.
Hope this helps!
