I have a problem about start the machine at podmanI am using ubuntu 20.04 serverI installed podman like this

echo "deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_20.04/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.listcurl -L "https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_20.04/Release.key" | sudo apt-key add -sudo apt-get updatesudo apt-get -y upgradesudo apt-get -y install podman

I need to start podman machine but I am getting an error

I am creating like this

root@ubuntu:# podman machine initExtracting compressed fileroot@ubuntu:# podman machine listNAME                     VM TYPE     CREATED         LAST UP         CPUS        MEMORY      DISK SIZEpodman-machine-default*  qemu        28 seconds ago  28 seconds ago  1           2.147GB     10.74GB

it looks fine when I tried to start the machine I have this

root@ubuntu:# podman machine startError: unable to start host networking: "could not find \"gvproxy\" in one of [/usr/local/libexec/podman /usr/local/lib/podman /usr/libexec/podman /usr/lib/podman]"

but I dont think there is something wrong with my podman installation because I can run a container

root@ubuntu:# podman run hello-worldResolved "hello-world" as an alias (/etc/containers/registries.conf.d/000-shortnames.conf)Trying to pull docker.io/library/hello-world:latest...Getting image source signaturesCopying blob 2db29710123e doneCopying config feb5d9fea6 doneWriting manifest to image destinationStoring signaturesHello from Docker!This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.    (amd64) 3. The Docker daemon created a new container from that image which runs the    executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it    to your terminal.To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID: https://hub.docker.com/For more examples and ideas, visit: https://docs.docker.com/get-started/
