While trying to run my Container Service Extension 2.6.1 after a successful installation. I kept getting the following error “Default template ubuntu-16.04_k8-1.15_weave-2.5.2_rev3 with revision 0 not found. Unable to start CSE server.”

To fix this you will need to:

1. Edit your CSE config.yaml file to include the right name of the default template and revision number. (Much more on this below)
2. Encrypt your CSE config file again
3. Re-Run CSE with your encrypted config file

In this post I will explain this in a bit more details for those hitting the same issue, as the resolution is quite simple but might not be as obvious if you are doing this for the first time.

For a start, here is what the exact error look like:
