Error when building sysroot image for arm64v8/ubuntu:focal

[petternorgren]

Problem

I run the command ros_cross_compile . --arch aarch64 --os ubuntu --rosdistro galactic and I get the error:

ERROR:Docker Client:Error building Docker image. The follow error was caught:
The command '/bin/bash -c echo 'Etc/UTC' > /etc/timezone &&     ln -sf /usr/share/zoneinfo/Etc/UTC /etc/localtime' returned a non-zero code: 127

I have tried changing the sysroot docker image file and from what I can tell it seems that the issue occurs since it can't find /bin/bash which seems odd.

Not sure how to proceed with this error. Does anybody have any suggestions?

Logs

Attached is the terminal output (for the part building the sysroot image):

Do you know what the value of BASE_IMAGE resolves to?

Hello @petternorgren do you find a solution? I have the same problem

[davidbro-in]

For me, it solves the problem docker run --rm --privileged multiarch/qemu-user-static --reset -p yes. But I do not know what it does.
