Comment 2 for bug 1934131

Could you please try to start privoxy again and if it fails again run the commands "systemctl status privoxy.service" and "journalctl -xe" with a wider screen after this to get more output.
The messages in DpkgTerminalLog.txt are cut at a place where it would become interesting...

Also have a look at /var/log/privoxy/*, maybe there is more information why privoxy fails.
