I'm trying to install Traefik on a Ubuntu 18.10 master on my cluster using Helm.

I'm able to install Helm with snap snap install helm --classic but then when I want to install Tiller with the helm init command, I have the following output :

helm init

Error: error installing: the server could not find the requested resource  

I've tried to install helm through the binaries from the official GitHub, it ends with the same error.

I've also tried to install Tiller manually by running :

helm init --dry-run --debug >> tiller.yml

But when I do kubectl apply -f tiller.yml, it says that it couldn't find extensions/v1beta1.

I'm running out of solutions so I'm asking for your help if you have any ideas !
