I'm unable to reproduce this problem on a clean install with no configuration - installing lighttpd and then visiting http://localhost brings up the default placeholder page.

What happens if you disable all your user-defined configuration files? Can you get the basic placeholder page up?

Travis Allen (travis-r-allen) wrote :

I had this problem. The workaround:

sudo apt-get install gamin

It appears that the default lighttpd configuration tries to use fam (aka gamin), but there is no dependency on gamin. I would suggest either the package adds a gamin dependency, or the default configuration removes the fam dependency.

That workaround fixed the problem for me too - turns out the image I was working with already had gamin installed. Purging gamin also removed lighttpd, then re-installed lighttpd produced the following:

Setting up lighttpd (1.4.35-4ubuntu1) ...
Job for lighttpd.service failed. See "systemctl status lighttpd.service" and "journalctl -xe" for details.
invoke-rc.d: initscript lighttpd, action "start" failed.

Same problem here with 15.10 beta:

lighttpd[5854]: /usr/sbin/lighttpd: symbol lookup error: /usr/sbin/lighttpd: undefined symbol: FAMNoExists

Installing gamin solves the problem, but kicks libfam0 out, maybe creating other problems elsewhere...

I was also affected by this issue on a quite fresh 15.10

Version: 1.4.35-4ubuntu1
Provides: httpd, httpd-cgi
Depends: libattr1 (>= 1:2.4.46-8), libbz2-1.0, libc6 (>= 2.15), libgamin0 | libfam0, libldap-2.4-2 (>= 2.4.7), libpcre3, libssl1.0.0 (>= 1.0.0), zlib1g (>= 1:1.1.4), init-system-helpers (>= 1.18~), perl, lsb-base (>= 3.2-14) | systemd (>= 29.1), mime-support, libterm-readline-perl-perl

apt pulled libfam0 by default and lighttpd got the undefined symbol raised.
Installing "gamin" instead solved the issue.

Still the same on Ubuntu 16.04 -- installing gamin solved it, though.

Will this ever get fixed?

Yep, install gamin solve this issue > it adds FAM libraries

Installing gamin fixes the issue. Please, please update the deps.

Ubuntu 17.04 and the problem remains!!!

Affects Ubuntu beta 17.10, 19th.Oct.2017 and replacing (lib?)fam with Gamin fixes it. 700+ days and counting..

I currently have this error in Ubuntu 16.04.3 LTS (recent fresh install)
works after installing gamin.

Same here, Ubuntu 16.04 LTS and ran into this problem immediately.
