Title: cupsctl can corrupt cupsd.conf if invoked by member of lpadmin group Status in cups package in Ubuntu: Confirmed Bug description: In Ubuntu 14.04 and 15.10, the sequence sudo cupsctl WebInterface=No sudo cupsctl WebInterface=Yes always does what it is supposed to, but if a member of the 'lpadmin' group invokes cupsctl WebInterface=No cupsctl WebInterface=Yes without 'sudo', /etc/cups/cupsd.conf will be corrupted to: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd";> <HTML> <HEAD> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8"> <TITLE>Web Interface is Disabled - CUPS v1.7.2</TITLE> <LINK REL="STYLESHEET" TYPE="text/css" HREF="/cups.css"> </HEAD> <BODY> <H1>Web Interface is Disabled</H1> <P>The web interface is currently disabled. Run "cupsctl WebInterface=yes" to enable it.</P> </BODY> </HTML> WebInterface Yes and the cups daemon will start malfunctioning instantly. This does not happen on CentOS or FreeBSD, so the Ubuntu package is not configured correctly.
