[solved ]Warning **: Error retrieving accessibility bus address:

[lambcutlet]

One issue I have always had was an error warning each time I started a python program from the commandline, for example 'python test.py'.

the warning

** (test.py:3047): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

to solve I installed 'at-spi2-core'

Code: Select all

sudo apt-get install at-spi2-core

i found the answer in this thread https://github.com/NixOS/nixpkgs/issues/16327

Thanks! That got rid of the annoying message whenever I started a python program.

You the man! This worked for me too. Thanks for posting the solution here!

at-spi2-core is on the list of "extra packages" I always install when building a new Raspbian disk.
That warning is not just a Python problem. For me it happens with all GTK+ applications (be they in Python or in C).

Using Debians STRETCH on the raspberry pi I received this error:

sudo apt-get update && apt-get dist-upgrade.....

So probably the at-spi2-core in not valid for the RPi - but I cannot find an alternative.
Any help on this please.

It is a fairly recent version of Raspbian.
