[Pkg-cups-devel] Bug#543468: cups: initscript displays a password prompt on startup, hangs.

[Hilko Bengen]

Package: cups
Version: 1.3.11-2
Severity: grave

While upgrading using aptitude (run through sudo), the upgrade process
hung on my machine:

    Setting up cups-bsd (1.3.11-2) ...
    Setting up cups (1.3.11-2) ...
    Installing new version of config file /etc/cups/cupsd.conf ...
    Installing new version of config file /etc/cups/cupsd.conf.default ...
    Installing new version of config file /etc/init.d/cups ...
    Starting Common Unix Printing System: cupsdPassword for root on printserver.company.invalid? 

After hitting RETURN, it resumed.

    cupsctl: Unauthorized
    .

I also get that password prompt when I do

    sudo /etc/init.d/cups start

The only place where that the only thing that references that
"printserver.company.invalid" host is the ~/.cups/client.conf in my
regular user's home directory. For an init script that should only care
about system-level configuration, this is clearly wrong.

Apparently, cups got found that file going through the HOME environment
variable. After unsetting the variable, the prompt is no longer shown.

Cheers,
-Hilko
