Dear Cygwin Team,

as far as I can tell the package "python" which drags in some python and 
creates a symlink like

/usr/bin/python -> python2.7.exe

has been removed recently (in the last 3 days or so) from the default 
package selection. This has the effect that calls to just "python" fail. 
Is this an intended change? I didn't see an announcement for this change 
here.

I hope, I can easily fix this by installing the package manually ...

Bets regards,

Michael

Dear Cygwin Team,

sorry - I was too quick. Actually the packages are the other way around:

New is:

python python-2.7.18-1.tar.bz2 0
python-pip-wheel python-pip-wheel-19.2.3-1.tar.bz2 0
python-setuptools-wheel python-setuptools-wheel-41.2.0-1.tar.bz2 0
python2 python2-2.7.18-2.tar.bz2 0
python27 python27-2.7.18-2.tar.bz2 0
python27-pip python27-pip-20.2.2-1.tar.bz2 0
python27-setuptools python27-setuptools-41.2.0-1.tar.bz2 0
python3 python3-3.8.6-1.tar.bz2 0
python36 python36-3.6.10-1.tar.bz2 0
python38 python38-3.8.3-1.tar.bz2 0

$ which python
which: no python in 
(/build/bin_special:/usr/local/bin:/usr/bin:/usr/x86_64-w64-mingw32/sys-root/mingw/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/usr/i686-pc-cygwin/sys-root/usr/bin)

Old is:

python-pip-wheel python-pip-wheel-19.2.3-1.tar.bz2 0
python-setuptools-wheel python-setuptools-wheel-41.2.0-1.tar.bz2 0
python2 python2-2.7.18-1.tar.bz2 0
python27 python27-2.7.18-1.tar.bz2 0
python3 python3-3.6.8-1.tar.bz2 0
python36 python36-3.6.10-1.tar.bz2 0

$ which python
/usr/bin/python

So I don't see an easy fix for this - short of creating the symlink 
manually.

Best regards,

Michael

strange, python27-2.7.18-2 postinstall script should have set
/usr/bin/python.
Same for the test packages

python36             3.6.12-2
python37             3.7.9-2
python38             3.8.6-2


$ which python
/usr/bin/python

$ ls -l /usr/bin/python
lrwxrwxrwx 1 Marco Administratoren 24 Dec 28 21:29 /usr/bin/python -> 
/etc/alternatives/python

$ alternatives --display python
python - status is auto.
  link currently points to /usr/bin/python3.8
/usr/bin/python2.7 - priority 27
/usr/bin/python3.8 - priority 38
/usr/bin/python3.6 - priority 36
/usr/bin/python3.7 - priority 37
Current `best' version is /usr/bin/python3.8.














can you try the test packages ?

Neither python27-2.7.18-1 or -2 have any postinstall script.

The change from -1 to -2 that causes python as such to disappear (which
I can confirm) is the loss of welded-in links:

my fault.
The postinstall scripts is in the wrong place
I will upload a a test version -3 shortly for python2(7)
