execution of chown(container files) get hung

Question

I'm trying to run Zalenium docker on ubuntu 18.04. Below is my command.

curl -sSL https://raw.githubusercontent.com/dosel/t/i/p | bash -s start

or

docker run --rm -ti -p 4404:4444 -v /var/run/docker.sock:/var/run/docker.sock -v /home/emiteqa/eMite/videos:/home/seluser/videos --privileged dosel/zalenium start

I got stuck at "Copying files for Dashboard"

Docker binary already present, will use that one.
Docker version 18.09.0, build 4d60db4
-- LOG 07:33:35:233537096 Ensuring docker works...
-- LOG 07:33:35:414698248 Ensuring docker-selenium is available...
haveged: haveged starting up
Copying files for Dashboard...

After investigate, I find the cause is the zalenium get hung at below line in zalenium.sh

sudo chown -R ${HOST_UID}:${HOST_GID} /home/seluser

Then, I go into the zalenium container. I try to run sudo chown on any file in the container, it get stuck.

What I have tried

• If I touch a new file and run sudo chown, there is no problem.
• If I CTRL+C and retry, it will pass.
• By using exact same steps starting from docker installation, I can run zalenium successfully on aws server.
• I googled, but didn't find any similar issue. I know it's possibly due to env issue, but I have no clue how to troubleshoot.

Thanks in advance for any suggestion and help.
