Falha ao conectar ao barramento de soquete

Question

Estou usando o ambiente do schroot para executar o python 32 bit na versão 17.10 do ubuntu de 64 bits.

(trusty_i386)root@sumonta-linux:/home# uname -a
Linux sumonta-linux 4.13.0-32-generic #35-Ubuntu SMP Thu Jan 25 09:13:46 UTC 2018 i686 i686 i686 GNU/Linux

Meu script python para verificação de conexão do Skype não está sendo executado e o erro fornecido abaixo. Alguém por favor me sugira o que eu estou fazendo errado?

Erro:
