sh: 0: Can't open deps.sh
The command '/bin/sh -c sh deps.sh ubuntu' returned a non-zero code: 127

Start with the Dockerfile steps around COPY and RUN sh deps.sh ubuntu, then inspect whether deps.sh is available in the copied build context. Reproduce the reported docker build command and trace why step 6 cannot open deps.sh; done means the installation build proceeds past that step.
