Repro Steps

1. Setup Podman on Ubuntu
   Follow the steps described in https://podman.io/docs/installation#debian .

sudo mkdir -p /etc/apt/keyrings

# Debian Testing/Bookworm
curl -fsSL https://download.opensuse.org/repositories/devel:kubic:libcontainers:unstable/Debian_Testing/Release.key \
  | gpg --dearmor \
  | sudo tee /etc/apt/keyrings/devel_kubic_libcontainers_unstable.gpg > /dev/null
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/devel_kubic_libcontainers_unstable.gpg]\
    https://download.opensuse.org/repositories/devel:kubic:libcontainers:unstable/Debian_Testing/ /" \
  | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:unstable.list > /dev/null

# Debian Unstable/Sid
curl -fsSL https://download.opensuse.org/repositories/devel:kubic:libcontainers:unstable/Debian_Unstable/Release.key \
  | gpg --dearmor \
  | sudo tee /etc/apt/keyrings/devel_kubic_libcontainers_unstable.gpg > /dev/null
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/devel_kubic_libcontainers_unstable.gpg]\

  | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:unstable.list > /dev/null

# Install Podman
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get -y install podman

2. Shutdown WSL2:

wsl --shutdown

3. Configure WSL2

Update ~/.wslconfig:

[experimental]
autoMemoryReclaim=gradual
sparseVhd=true

4. Start WSL and run podman command

podman run busybox ls

Expected Behavior

$ podman run busybox ls
WARN[0000] "/" is not a shared mount, this could cause issues or missing mounts with rootless containers
bin
dev
etc
home
lib
lib64
proc
root
run
sys
tmp
usr
var

Actual Behavior

$ podman run busybox ls
WARN[0000] "/" is not a shared mount, this could cause issues or missing mounts with rootless containers
Error: OCI runtime error: crun: cgroups in hybrid mode not supported, drop all controllers from cgroupv2

Diagnostic Logs

Commenting out autoMemoryReclaim from ~/.wslconfig on host Windows11 solves the error and podman runs as Expected Behavor.

cat ~/.wslconfig
[experimental]
#autoMemoryReclaim=gradual
sparseVhd=true

Thanks for reporting, you may want to use dropcache instead of gradual for the time being.

@pmartincic Thank you! podman runs as expected with dropcache.
