[pkg-lighttpd] Bug#451242: installaion fails if other web server is running

[Bas Zoetekouw]

Package: lighttpd
Version: 1.4.18-1
Severity: serious

When trying to install httpd with a runnign apache, I get this:

Setting up lighttpd (1.4.18-1) ...
Starting web server: lighttpd2007-11-14 13:31:18: (network.c.300) can't bind to port:  80 Address already in use 
 failed!
invoke-rc.d: initscript lighttpd, action "start" failed.
dpkg: error processing lighttpd (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 lighttpd
E: Sub-process /usr/bin/dpkg returned an error code (1)

In this case, it is _correct_ behaviour that lighttpd doesn't start (I
want it to run at a different port), so the postinst should not
fail but rather just warn the user.
