Can not start httpd (apache), missing mod_dnssd.so

[Dimitrij Mijoski]

OS: Ubuntu 17.10
Version: 3.14.2-2ubuntu5

Steps to reproduce:

1. Open terminal and run:
gnome-file-share-properties

2. Tick Share public files on network

3. In terminal see the error message:
apache2: Syntax error on line 21 of /usr/share/gnome-user-share/dav_user_2.4.conf: Cannot load /usr/lib/apache2/modules//mod_dnssd.so into server: /usr/lib/apache2/modules/mod_dnssd.so: cannot open shared object file: No such file or directory

Alternative steps to reproduce:
1. In terminal run
gnome-control-center sharing

2. Enable File sharing

3. Same message appears

Installing libapache2-mod-dnssd resolves the issue. BUt i had to do it manually.

Ideally, when enabling the feature a window should pop that pull the needed dependencies. Same as enabling the samba sharing.

gnome-user-share depends on libapache2-mod-dnssd in Ubuntu 18.04 LTS.

Ubuntu 17.10 is no longer supported so I am closing this bug.

This is still an issue in Ubuntu 19.10 (Eoan).

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem on 19.10 and can't find a fix after hours and hours of googling.
