[scottrudy]

Issue Description

Podman 5.3.0 on Windows throws exception on missing path when run.

Steps to reproduce the issue

Steps to reproduce the issue

1. In my case I had 5.2.5 installed via winget (pretty vanilla install) and upgraded using winget upgrade --all
2. the podman machine would start, but when trying issue a podman ps -a and other commands I would get a connectivity error
3. logging into the machine allowed podman ps -a to work fine
4. I uninstalled the machine and podman and then reinstalled 5.3.0 directly, but faced the same issue

Describe the results you received

Cannot connect to Podman. Please verify your connection to the Linux system using podman system connection list, or try podman machine init and podman machine start to manage a new Linux VM
Error: unable to connect to Podman socket: open C:\Users{username}.ssh\known_hosts: The system cannot find the path specified.

Describe the results you expected

I expected to see the containers on the machine

Additional information

I was able to eventually workaround the issue by adding an empty C:\Users\{username}\.ssh\known_hosts file, but given that the file is 0 bytes, it doesn't seem like it's something the podman command should fail on or at least possibly the installer could touch the file to ensure it exists.

per #24650 , I believe this is only the lack of the ~/.ssh directory itself. I added that directory with mkdir and the known_hosts was created as expected. I will close #24650 as a dup.

Confirmed.
