Hmm, that's interesting, the exit code is 0 which means OK doesn't it?

 >>> System start/stop links for /etc/init.d/apache2 already exist.
 >>> 0

I just tried running the whole script and it returns 0...

 >>> r0g at steppa:/var/lib/dpkg/info$ cd /var/lib/dpkg/info/
 >>> r0g at steppa:/var/lib/dpkg/info$ sudo ./apache2.2-common.postinst; 
echo $?
 >>> 0

I didn't know how to display the error code before so thanks for that :)

I just ran update manager again and it came back with "Your system is up 
to date" but I think that's because all the other updates installed OK, 
reassuringly. I don't know if it will happen again next time I have 
updates to install, it has done the last few times I did but I guess 
I'll have to wait and see now.

Thanks for your help,

Roger.
