• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Debian stretch docker container, Arch host

• Poetry version: 1.1.4

Issue

When trying to install the dependencies with poetry for my project in a docker container, poetry just exits with no errors or warning, just an exit code of 1.

The Dockerfile is https://github.com/bitcoin-core/HWI/blob/def565b5ac5d98b5fcc453328fc9a20207c6e00a/contrib/build.Dockerfile and the script being run is https://github.com/bitcoin-core/HWI/blob/def565b5ac5d98b5fcc453328fc9a20207c6e00a/contrib/build_bin.sh. It specifically errors on the line poetry install -E qt. Changing this command to include -vvv does not effect the output.

The output is

+ poetry install -E qt

This previously worked when poetry 1.0.10 was used and it seems like 1.1.0 is the version where this stopped working.

If I run this on my host, also with 1.1.4, there are no issues. It seems to only be in this container. The script doesn't seem to make a difference; I can have a shell in the container, do poetry install manually, and it still fails in the same way.
