[Python-apps-team] Bug#919752: mu-editor: Explain better what is wrong when micropython firmware is missing?

[Nick Morrott]

The root cause of this issue rests with the way mu-editor is currently packaged.

Upstream, mu-editor contains not just the editor but also uflash and
the compiled MicroPython hex, so flashing the micro:bit works out of
the box.

In Debian, such bundling is not permitted, hence I have split out out
uflash and MicroPython into their own packages. The placeholder
firmware-microbit-micropython-dl package (provided by python3-uflash)
sits in contrib, so cannot be added as a hard dependency on mu-editor.

Once firmware-microbit-micropython is accepted into unstable (it is
now in NEW) I can update the dependencies to ensure it is installed
with the editor and avoid the issue you raise in this report.

Thanks,
Nick
