Describe the results you received:

Error: Unable to connect to Podman socket

Describe the results you expected:

  • Expected to see the same or similar output as Step 3. above.
  • Podman commands in the remote client are executed on the podman-machine-default machine on WSL2

Additional information you deem important (e.g. issue happens only occasionally):

This issue happens on a fresh install of the machine and client.

Output of podman version:

Client:       Podman Engine
Version:      4.3.1
API Version:  4.3.1
Go Version:   go1.18.8
Built:        Thu Jan  1 07:30:00 1970
OS/Arch:      linux/amd64

Output of podman info:

# Please refer to above for both the machine and client.

Package info (e.g. output of rpm -q podman or apt list podman or brew info podman):

$ which podman
/usr/local/bin/podman

Podman was build on docker image which is imported as WSL2 distribution using EasyWSL tool.
Following is the Dockerfile used to build the image:
