The [sometimes] trouble with updates

No, I am not referring to Windows updates. Instead, I am referring to Linux updates. There are mixed views on whether you should do updates or not on your system(s). Here is my view.... if it is a server, update it ONLY when you are absolutely needing to. This means only if there is a security hole that is fixed by a newer version. On the other hand, if it is a desktop system, if you update then it is up to you.

If you do updates though, you really need to watch out. Make sure you know what exactly is happening during the update(s) as things tend to change and also stop working.

I did an update earlier this evening after booting up my laptop. No worries, right? Wrong. When I tried to start my apache web server (which was previously installed and working fine), I discovered that it was no longer working. Strange if you ask me, but it wasn't starting up. It kept giving me the same errors:

# /etc/init.d/apache2 start
* Starting web server apache2 [Fri Oct 24 22:15:10 2008] [warn] module php5_module is already loaded, skipping
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

I started by plugging in the different errors into Google, but kept going in directions I didn't think were the answer. Then I looked at the last error: "Unable to open logs". That was odd because I hadn't changed anything, but...... then there was the updates.

So I checked and the /var/log/apache2 directory and saw that it was owned by root and had a group of adm. I distinctly remember that being the group root the other day. So, instead of changing permissions (which is someting I was not wanting to do, I decided to add root to the adm group.

I restarted apache and VOILA!!! Problem fixed. So, the lesson.... know what updates are being applied and if something doesn't work afterwards, you will at least know why.
