Bug#991674: unblock: python-uflash/1.2.4+dfsg-8
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
Please unblock package python-uflash
[ Reason ]
The upload fixes RC bug #991280.
Source package python-uflash provides a convenience package
(firmware-microbit-micropython-dl) which downloads a pre-compiled
MicroPython runtime for the micro:bit computer.
The downloaded file is checksummed to ensure it is compatible with
the installed version of python3-uflash; the package will fail to install
on checksum error (as seen in the bug report).
During the bullseye hard freeze, upstream replaced this file with a new
runtime that supports a new version of the micro:bit computer that is not
supported by our packages in bullseye. The changed file has a different
checksum, and fails to install, causing the package installation to
abort. Bug report #991280 was received after bullseye went into full
freeze.
[ Impact ]
Very serious for users of mu-editor, as the editor would be removed from
bullseye as a result of its dependency on python3-uflash. mu-editor is
a popular editor used globally by children and adults learning Python,
with increasing popularity indicated by popcon.
Bullseye provides the separate firmware-microbit-micropython package,
which is a Recommended dependency of python3-uflash and which almost
all users will install. Only a tiny proportion of users install the
affected -dl package.
However, all mu-editor users will be affected if the updated package
does not migrate and mu-editor is removed from bullseye.
[ Tests ]
The firmware-microbit-micropython-dl binary package has been tested
locally to ensure that it downloads the correct runtime file. There
are no upstream code changes at all; autopkgtests are unaffected and
still pass.
[ Risks ]
The debdiff is trivial: one updated URL to ensure the correct file is
downloaded on package installation.
There are no changes to any upstream code.
No other packages are impacted by this change.
The affected binary package (firmware-microbit-micropython-dl) is a
leaf package, and is only Suggested by python3-uflash.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
[ Other info ]
The offending binary package (firmware-microbit-micropython-dl) was added
to Debian during the buster development cycle to improve the end-user
experience whilst the firmware-microbit-micropython package was being
developed. Most mu-editor/uflash users will not install it.
