Ubuntu:full-20.04 - mkdir: Permission denied, cannot create directory _actions.

I am executing this image with act.

When I use the version catthehacker/ubuntu:full-20.04 it is failing at the start because it is running as the use runner and not as a root.

Note: Interesting the original GitHub action is executing as a runner that means this copy is very similar to the original (https://github.com/airvzxf/bose-connect-app-linux/runs/2596465956).

[catthehacker]

That's because act does not supports running actions as non-root account.

[airvzxf]

Do you know how to use your image to test my GitHub work flow?
I really was very disappointed to the null solutions to test locally the workflows. I used GitLab, it has basically the same problem but at least I can get the official setup and images.

[catthehacker]

It can probably work if you change default user via docker build

FROM catthehacker/ubuntu:full-20.04
USER root

or older versions of act should work since those used static path for project

[catthehacker]

Should be fixed in act soon

[catthehacker]

Fixed in nektos/act@d794e2f

Thank you, Hacker Cat!
