Detailed Description

Port to Python 3 via the Six environment.

Security updates and upstream support for Python 2 are due to be withdrawn, and this will prevent running Sugar on Linux.

Downstream distributions are removing Python 2 packages.

Benefit to Sugar

Benefit to the platform is continued availability. Activities will have access to Python 3 language features. Systems with Python 2 available will continue to run Python 2 activities.


Components to be changed include datastore (carquinyol), toolkit (sugar3), gwebsockets, artwork, shell (jarabe), and Sucrose activities.

Specific changes are tracked at https://github.com/orgs/sugarlabs/projects/1

UI Design

No UI impact.

How To Test


User Experience

Systems without Python 2 available will have a severe reduction in available activities.



Contingency Plan

None. Sugar will be in jeopardy.



Release Notes

Sugar is ported to Python 3.
