Docker support

[firewave]

If you try to use this in an action which will be run inside a container

    container:
      image: "ubuntu:21.04"

it will fail since sudo is not available

Run jurplel/install-qt-action@v2
  with:
    modules: qtcharts
    version: 5.15.2
    target: desktop
    install-deps: true
    cached: false
    setup-python: true
    set-env: true
    tools-only: false
    aqtversion: ==1.1.3
    py7zrversion: ==0.14.0
/usr/bin/docker exec  f448ac4ce4ccb3756862341c12dd51458dce4d7849d6343c22875989be917835 sh -c "cat /etc/*release | grep ^ID"
Successfully setup CPython (3.9.4)
sudo apt-get update
Error: There was an error when attempting to execute the process 'sudo'. This may indicate the process failed to start. Error: spawn sudo ENOENT

sudo is not necessary here since it will be executed with a user that has all privileges.

After wrestling with some random bug for an hour, you can now use nosudo with install-deps for this behavior

[firewave]

Thanks a lot for the amazingly fast reply. I will apply the change tomorrow.

Unfortunately the change broke the default behavior because of a copy-and-paste error. :(

[jurplel]

Okay that was pretty bad, sorry about that. Should be fixed now.

ImportError: libffi.so.7: cannot open shared object file: No such file or directory
Error: The process 'python3' failed with exit code 1

Seems like there is a missing dependency. Not sure where the error is located.

dpkg -S libffi.so.7
libffi7:amd64: /usr/lib/x86_64-linux-gnu/libffi.so.7.1.0
libffi7:amd64: /usr/lib/x86_64-linux-gnu/libffi.so.7

Installing the package manually fixes it.

I would change the ticket name to reflect this is actually about docker support.

[jurplel]

apt-get installing libffi-dev should fix this, yes?

[firewave]

libffi7 is the package in question - as seen in the dpkg output.

[jurplel]

I think it is out of scope for this action to install that, because that package is only for ubuntu 20.04 and 21.04. Maybe try passing setup-python: false to install-qt-action and install python with the apt command beforehand.

[firewave]

That package probably changed in-between distros. I think the problem stems from the package being installed by pip instead by the system package python3-cffi (or whatever it is called) and it being a minimized docker image. I might take a look into it but I am really pressed for time at the moment.

If this is not done within the action it should probably be mentioned somewhere in the documentation that you are required to install that package when using docker or downsized distros.

[jurplel]

Well, depending on what the user is doing, there are all sorts of packages that need to be installed, and of course these are all different between distros. Documenting edge cases like this would be an exercise in futility. The only thing that I can guarantee works out of the box is using Github's runners

[firewave]

I didn't expect that the packages are mentioned in detail - just that there might be such cases - to avoid bug reports...hopefully :-)
