Error upgrading Podman

If you are using Podman Desktop, you are in fact using a combination of 2 tools. One is Podman, an open source container, pod, and container image management engine.

The other is Podman Desktop itself which is a graphical layer on top of Podman (and other container engines).

Podman Logo

This means that you can use different versions of Podman in combination with different versions of Podman Desktop.  For example, as you can see in the screenshot below I’m using version 5.2.0 of Podman whereas my Podman Desktop version is v1.12.0.

Error: vm "podman-machine-default" already exists on hypervisor

Today after upgrading Podman, Podman Desktop started to return the following error message when I tried to initialize the podman virtual machine:

Error: vm "podman-machine-default" already exists on hypervisor


I tried to fix it by removing the virtual machine distribution from wsl:

wsl --unregister podman-machine-default

When I tried to initialize the podman virtual machine again, it failed again but with a different error message:

Error extracting compressed file: \"unexpected EOF\"" Error: unexpected EOF

To fix that problem I had to reset the virtual machine:

podman.exe machine reset
Warning: this command will delete all existing Podman machines and all of the configuration and data directories for Podman machines
The following machine(s) will be deleted:

Are you sure you want to continue? [y/N]

Now I could re-download and initialize the virtual machine successfully:

podman.exe machine init
Downloading VM image: v20240728061533-5.1-rootfs-amd64.tar.zst: done
Extracting compressed file: podman-machine-default-amd64: done
Importing operating system into WSL (this may take a few minutes on a new WSL install)...
Import in progress, this may take a few minutes.
The operation completed successfully.
Configuring system... Machine init complete

To start your machine run: podman machine start

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 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: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
