Installation Failed on local machine due to docker-compose

Tutor

Can someone tell me why this is happening during “tutor local quickstart” ?? I am not that proficient with docker or docker-compose.
My PC: ASUS TUF Gaming A15 with UBUNTU latest version (20.04 as of now).

Error Showing in terminal:

Did you install this via pip or via the binary?

from pip install I get the error from the oneclick binary I don’t

3

@max_fletcher as suggested by the troubleshooting docs, are you able to run the following command? (not as root, but as a regular user)

docker run --rm hello-world
4

I tried both. I believe both shows the same problem which is twice as frustrating.

5

Yes. That runs perfectly fine.

6

Check the outgoing firewall to make sure its open for udp and tcp requests.

This does not look like an issue related to Tutor, but more to docker-compose. What is your version of docker and docker-compose?

docker --version
which docker-compose
docker-compose --version
8

docker --version gives me this:
Docker version 20.10.6, build 370c289
docker-compose --version gives me this:
docker-compose version 1.29.1, build c34c88b2

BTW will it be a huge problem if I use pip3 to install docker and docker-compose ?? Mine didn’t work work with just pip at the time so used pip3 instead.

@max_fletcher Are you 100% sure that docker run --rm hello-world is working? This should work NOT as sudo user, but as the same user that you are using to run tutor. To convince us, please paste here the exact command and the full output of the following exact command:

echo $UID && docker run --rm hello-world

Please forgive my doubts, but the behaviour you are observing is quite surprising to me.
