libapache2-mod-mono fails to preconfigure

[John Ryan]

Binary package hint: libapache2-mod-mono

When trying to install libapache2-mod-mono for the first time, the package fails to preconfigure because the file /etc/apache2/mod-available/mod_mono.conf is not available. It will be installed by the libapache2-mod-mono package. The installation output is given below:

user@host:/etc/mono-server2$ sudo apt-get install libapache2-mod-mono

Workaround:
To ensure a clean install, you can simply remove (don't autoremove or purge) the package and re-install:

sudo apt-get remove libapache2-mod-mono
sudo apt-get install libapache2-mod-mono

Because /etc/apache2/mod-available/mod_mono.conf now exists, the second installation will complete cleanly.

Cause:
The two lines running 'sed' in the following section of the config script in the installation package should be enclosed by a check for the existence of the file /etc/apache2/mods-available/mod_mono.conf:

# Change the includes as appropriate
MONO_CONF=/etc/apache2/mods-available/mod_mono.conf

case "$USE_MONO_SERVER" in
    none)
 # Can't find anything
 echo "Either mono-apache-server or mono-apache-server2 needs "
 echo "to be installed."
 exit 1
 ;;
    mod-mono-server)
 echo "Using mono-apache-server..."
 sed 's@^Include.*$@Include /etc/mono-server/mono-server-hosts.conf@' \
     < $MONO_CONF > $tempfile
 cp -f $tempfile $MONO_CONF
 rm -f $tempfile
 ;;
    mod-mono-server2)
 echo "Using mono-apache-server2..."
 sed 's@^Include.*$@Include /etc/mono-server2/mono-server2-hosts.conf@'\
     < $MONO_CONF > $tempfile
 cp -f $tempfile $MONO_CONF
 rm -f $tempfile
 ;;

Could not reproduce this on hardy

I can reproduce this on gutsy as well as on hardy.

However, it seems to me that the error is just displayed and the installation is nevertheless continued and successfully completed.
