I'm getting this error with orderer while launching a Fabric v2 network

Channel capability V2_0 is required but not supported

My configtx.yaml's Capabilities section

Capabilities:
    Channel: &ChannelCapabilities
        V2_0: true
    Orderer: &OrdererCapabilities
        V2_0: true
    Application: &ApplicationCapabilities
        V2_0: true

Generated channel artifacts with configtxgen v2.0.0 

 $ configtxgen --version
configtxgen:
 Version: 2.0.0
 Commit SHA: 0432c3e80
 Go version: go1.13.4
 OS/Arch: linux/amd64

Using hyperledger/fabric-orderer:latest docker image.

Any suggestion what I might be doing wrong?

The latest tag points to the 1.4 image, not the 2.0 image. I can't remember exactly what the discussion around the latest tag was but I don't believe its planned to be updated, ie it's intentional that latest hasn't been changed to point to 2.0

Met the same problem, specified orderer and tools image tag to 2.2 and it works.
