wsl integration no longer works - docker socket not found

Description

I can no longer access docker from my wsl distribution since today.
Confirmed to happen after upgrade to Docker Desktop v4.39.0.

Reproduce

run docker info from wsl

Expected behavior

docker info should be able to talk to the daemon.

Confirmed to happen after upgrade to Docker Desktop v4.39.0. Rolling back to v4.38.0 works

I have this same issue. Stupidly upgraded back to v4.39.0 and issue starts again.

Same issue, rolling back to v4.38.0 worked for me as well

Same issue, rolling back to v4.38.0 worked for me as well

I also have this issue.

Every time I try to rollback, within a few hours I'm back on 4.39.0. Talked to our IT team and they don't have anything forcing it to update and I have both update checkboxes unchecked:

Think about what will you do when 4.40.0 released? From 4.27 to 4.39, so many times, nearly every release have severe problems.
I'm done.
Try podman desktop.

I removed Docker Desktop and installed docker and docker engine inside WSL2. It worked fine afterwards.

Uninstall Docker Desktop
Run this command inside WSL2:

sudo apt update
sudo apt install -y \
  ca-certificates \
  curl \
  gnupg \
  lsb-release

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
  sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
  https://download.docker.com/linux/ubuntu noble stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

start docker service: sudo dockerd
test if it works:

docker version
docker run hello-world

I don't know why, I had to run this again in order for docker compose to work

sudo apt update
sudo apt install docker-compose-plugin

Has anybody testd v4.40.0?

Has anybody testd v4.40.0?

Nope, still an issue on v4.40.0

I have a similar issue. Docker Desktop starts normally and works for a while. Then about after an hour, I suddenly lost ability to run any Docker related commands in WSL2 via the command line. Instead I get the error:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

The containers are still running, and in my case I can still access the related web services the containers expose. I just can't seem to control them via WSL2

docker context ls output:

Here's a dev build to try. Let me know how you get on!

https://desktop-stage.docker.com/win/main/arm64/202689/Docker%20Desktop%20Installer.exe

This looks like it may be an ARM64 binary and I am unable to install it for testing on my AMD64 system.

Oh yes, sorry about that!

Here's the right one for amd64:

It's working on my side, Debian 13 in WSL2 ;)

Awesome news!

Looks to be working on my Ubuntu 25.10 WSL2 instance.

Thanks for reporting back.

The fix should make its way in to the next official release!

Just as a last report back I ran through the debugging steps throughout the thread and everything looks good:

$ ls -al /var/run/docker*

Though redundant I also verified that I could see the expected files in \\wsl.localhost\Ubuntu\run on the Windows host.

works again with official release: 4.45.0 (203075) 🥳

@chelnak

@chelnak Any reason for this fix not being mentioned in official release notes of 4.45.0?

Oh! It must have been missed.. I'll get that updated.

@lorenrh

PR open -> docker/docs#23339 (thanks @lorenrh)

This problem has returned in version 4.75.0

docker compose up -d
unable to get image 'phpmyadmin/phpmyadmin': failed to connect to the docker API at unix:///var/run/docker.sock; check if the path is correct and if the daemon is running: dial unix /var/run/docker.sock: connect: no such file or directory

Solved: I just found in the release notes that WSL integrations were disabled, and I needed to turn them on again.

Tysm! To be more specific, I needed to go to Settings > Resources > WSL integration and tick the Enable integration with my default WSL distro checkbox.
