Description Klaus Pedersen 2019-01-03 10:30:03 UTC

Description of problem:

sagemath's classic notebook doens't work on Fedora 29 (bug 1640890). And to
use the newer Jupyter based notebook, the classic notebooks have to be
'exported'.

Unfortunately export doesn't work either.


Version-Release number of selected component (if applicable):

sagemath.x86_64                        8.3-1.fc29


How reproducible:

Every time.


Steps to Reproduce:
1. Install sagemath and all missing dependencies (bugs 1464520, 1636759, 1657825)
2. Then enter "sage -n export --list" or "sage-export"


Actual results:
[...]
  File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 781, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'configparser>=3.5; python_version == "2.7"' distribution was not found and is required by entrypoints


Expected results:
admin:0         | Near-field coil OBW
admin:1         | UV auto flow
admin:2         | Band gap vs temperature
[...]


Additional info:
After many days of archlinux forums, bing, stackoverflow, etc - only one
generally approved solution was found: uninstall all python backports
packages and the configparser. 

That would uninstall half the world, including texlive, python2, etc. Anyway
I tried of desperation :-(

> $ dnf erase python2-configparser
> [...]
> Remove  286 Packages
> Freed space: 1.7 G

But is still didn't fix the problem...


This one crazy hack worked:

It occured that the error message looked strange:

>    'configparser>=3.5; python_version == "2.7"' distribution was not found
    
True enough, that exact string is found in: []/entrypoints-0.2.3.dist-info/METADATA, file:

> Requires-Python: >=2.7
> Classifier: License :: OSI Approved :: MIT License
> Requires-Dist:  configparser (>=3.5); python_version == '2.7'

Removing the Requires-Dist parameter fix the problem:

- Requires-Dist:  configparser (>=3.5); python_version == '2.7'
+ Requires-Dist:
+ # configparser (>=3.5); python_version == '2.7'

Comment 1 Jerry James 2019-01-18 21:35:21 UTC

This is not a sagemath bug.  The problem is that python2-entrypoints requires version 3.5 or greater of python2-configparser, but Fedora provides only a beta version: 3.5.0b2.  Either the entrypoints package needs to relax its version requirement on configparser or (ideally) configparser must be upgraded to the final 3.5 release or later.  See bug 1588035.
