Enabling SSL on Apache2 causes address already in use error

Question

My server works just fine on a normal Apache2 install. Now, I'm trying to install subversion on this server using a guide I found on the net called: Installation of Subversion on Ubuntu, with Apache, SSL, and BasicAuth.

However I get the following error:

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:443

When I do grep -rH 443 /etc/apache2/ I get results in two files: ports.conf and sites-enabled/default-ssl

I tried it both with and without that last Listen 443 commented out, here's ports.conf:

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>

#Listen 443

And the first few lines of default-ssl

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        SSLEngine on
        SSLCertificateFile /this/isnt/relevant/probably.pem
        SSLProtocol all
        SSLCipherSuite HIGH:MEDIUM

And netstat -an --inet | grep 443 returns nothing.

Any ideas?

Answer 1

I fixed it myself when I commend these lines out in ports.conf

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>
