Report #74969

[bug\_fix] ERROR: failed to solve: process "/bin/sh -c ..." did not complete successfully: exit code: 1

Run the docker build command with the --progress=plain flag to disable the TUI and expose the full build logs.

Journey Context:
A developer runs a Docker build and it fails. BuildKit shows a fancy, condensed terminal UI \(TUI\) and just says the process did not complete successfully with exit code 1. The developer tries to scroll up, but the TUI overwrites the output. They try redirecting stderr to a file, but it's full of ANSI control characters and cursor movement sequences. They need the actual error from the RUN step to debug. The established way to bypass this is to run the build with '--progress=plain'. This disables the TUI and prints the raw, sequential logs to the terminal, making the actual compiler or package manager error visible.
