Currently python3 is a meta-package whose main purpose is to require the default python version (currently python38). Marco, couldn't you just make python3-foo a meta-package that requires the corresponding python*-foo (currently python38-foo)? the issue is that Cygport creates the "obsolete" python3-foo that is replaced by python36-foo automatically. we should change cygport to use python38 instead --- $ cat python3-lxml/python3-lxml-4.6.2-1.hint category: _obsolete requires: python36-lxml sdesc: "Obsoleted by python36-lxml" ldesc: "The python3-lxml package is obsolete. Selecting this package for installation will cause the python36-lxml package, which replaces this one, to be installed instead." external-source: python-lxml --- As long as you have to patch cygport anyway, maybe it would be better to have cygport create an empty (but not obsolete) package. I think users might find it confusing that they have to install an obsolete package to get what they want. Also, obsolete packages are normally hidden in the setup UI. Yeah. I've wanted to improve how things in this area for a while (since there are some checks which calm does for 'should this package be obsolete') which are thwarted by this kind of package. So, I've added 'Virtual' to the list of package categories that calm permits, if you want to use it for this kind of meta-package. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

Umbrello UML Modeller (KDE)
Hello, I report a build success for current Umbrello master [1]. Beyond the dependencies listed at [3] I needed to install the following packages: - cmake - extra-cmake-modules (ECM) - kf5-kdesignerplugin - libKF5Emoticons-devel - kf5-kinit-devel For configuring and building I followed the steps in the section "Source Code on Linux like operating systems" for building with Qt5/KF5 at [2]. By the way, the Umbrello package page at [3] says "maintainer(s): ORPHANED" Is there a way to get that page updated?

[ANNOUNCEMENT] Updated: python packages
Several python packages have been updated
python{37,38}-h5py-3.2.1-1
python{36,37,38}-pip-21.1.1-1
or added
python{36,37,38}-pytest-env-0.6.2-1
python{36,37,38}-pytest-sugar-0.9.4-1
python{36,37,38}-termcolor-1.1.0-1
CYGWIN CHANGES
As python2 is no longer supported
https://devguide.python.org/devcycle/#end-of-life-branches
the package are updated to include postinstall script that
use "alternatives" to define for
/usr/bin/python
/usr/bin/python3
/usr/bin/idle3
/usr/bin/pydoc3
a default to the highest package available.
$ alternatives --display python
python - status is auto.
link currently points to /usr/bin/python3.8
/usr/bin/python3.7 - priority 37
/usr/bin/python3.8 - priority 38
/usr/bin/python3.6 - priority 36
/usr/bin/python2.7 - priority 27
Current `best' version is /usr/bin/python3.8.
The following link are not provided anymore.
/usr/bin/idle
/usr/bin/pydoc
The python3 package will pull python38 package.
Rationale:
https://www.python.org/dev/peps/pep-0394/
In other systems as Debian
/usr/bin/python is discouraged.
As on Cygwin we have still several third packages depending on
python2, the usage of alternatives should allow to manage
until all are updated to python3
DESCRIPTION
Python is a programming language that lets you work quickly
and integrate systems more effectively.
Python is powerful... and fast; plays well with others;
runs everywhere; is friendly & easy to learn; is Open.
