This helped me - https://support.circleci.com/hc/en-us/articles/360035524354-CircleCI-CLI-unable-to-connect-to-docker-on-Ubuntu-19-04-

I didn't reinstall docker, only circleci cli:
sudo snap remove circleci
sudo snap install --devmode circleci

I'm on Ubuntu 19.10.

Update:
I got another error saying "Error: failed to start event processor: failed to compute task config: failed to read config file: read /tmp/local_build_config.yml: is a directory". It's also caused by the limitation of snap installation, so I had to:
sudo snap remove circleci
curl -fLSs https://raw.githubusercontent.com/CircleCI-Public/circleci-cli/master/install.sh | sudo bash (alterantive installation option found at circleci website)

Now I can run the jobs locally.

I'm still unable to connect to docker on ubuntu 20.10. Installing circleci in devmode did not help, and the curl->bash install also did not help. docker version is fine. Can anyone suggest further debugging steps?

[hadi-alnehlawi]

thanks @amatveiev. isn't there any update from circleci team yet?

[jamierpond]

Yeah, also stuck on this issue, Mac arm64, Monterey

[jamierpond]

On macOS, the thing for me was that I couldn't use the brew install docker, I had to use the desktop docker app.
