Current status
- Targeted release: Fedora 30
- Last updated: 2018-09-04
- Tracker bug: <will be assigned by the Wrangler>
Detailed Description
On Fedora 27 to 29, FreeIPA client and server packages use Python 3 default. Additionally FreeIPA provides Python 2 packages. The Python 2 packages are not used by FreeIPA, but are merely provided for backwards compatibility, e.g. Python 2 applications that python2-ipaclient to communicate with a FreeIPA server.
The FreeIPA upstream project is going to drop support for Python 2.7 in the upcoming FreeIPA release 4.8.0. Python 2 support is not only causing development and testing overhead. It's also blocking improvements like new 389-DS installer, use of new Python features, and more. The removal of Python 2 support was announced on the FreeIPA development on 2018-09-03.
Removed packages
- python2-ipalib
- python2-ipaclient
- python2-ipaserver
- python2-ipatests
