Haproxy error code


What is the problem?
During an update, I got a message in terminal.

Setting up libraspberrypi-bin (1.20170703-1) ...
Setting up raspi-config (20170705) ...
Installing new version of config file /etc/init.d/raspi-config ...

Processing triggers for systemd (215-17+deb8u7) ...
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

What does it mean? And how can I solve it please? It seems that Haproxy is not working because of it. Thank you!
