but i can use it anyway

[mamoodi]

Weird. That's good that you can still use it.
What linux dist are you running?

[mamoodi]

Oh wait I'm getting this too when attaching my local filesystem.

[NICK-DUAN]

Weird. That's good that you can still use it. What linux dist are you running?

Tencent Linux, seems like ≈Centos6.6

# uname -r
6.6.26-1.0.tl4.x86_64

[NICK-DUAN]

I did nothing, but seems this problem is gone, then I still want to why, if you know, please tell me

[mamoodi]

I think this happens when you attach a filesystem to OpenHands. I got it yesterday multiple times.

[NICK-DUAN]

But I still attach a filesystem now LOL, By environment:

export WORKSPACE_BASE=$(pwd)

docker run xxx \
    -e WORKSPACE_MOUNT_PATH=$WORKSPACE_BASE \
    -v $WORKSPACE_BASE:/opt/workspace_base \
    xxx

[mamoodi]

haha that's strange. Unsure but let's keep an eye on this.

[mistermjtek]

Hello OH team, just built the docker image from scratch and ran it for the first time using the Quickstart command from the README - also experiencing the same error. To be clear, I didn't attach a filesystem to OH.

docker run -it --rm --pull=always \
    -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:0.26-nikolaik \
    -e LOG_ALL_EVENTS=true \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v ~/.openhands-state:/.openhands-state \
    -p 3000:3000 \
    --add-host host.docker.internal:host-gateway \
    --name openhands-app \
    docker.all-hands.dev/all-hands-ai/openhands:0.26

After running this, I get the same error mentioned by @NICK-DUAN.
