I upgraded my webserver to Debian Lenny last night. It went almost without
problems. This was because I followed the release notes. This helped a whole
lot.
Still this morning there was a small problem that I didn't notice yesterday. I
didn't receive any email. So I took a look in the exim4 mainlog at
/var/log/exim4/mainlog. It contained the following message:
lowest numbered MX record points to local host: servername
All messages that should be delivered in a local mailbox were frozen. The
solution was actually quite simple. First I needed to change one line in a
config file. It contained something that looked like: DEBCONFxxxDEBCONF. This
is a line that would normally be replaced by the update-exim4.conf script.
But that doesn't work anymore.
Now the files conf.d/main/005_local_hostnames contains a line like this:
MAIN_LOCAL_DOMAINS = localhost:servername:dsearch;/etc/exim4/virtual
All hostnames on this line should be delivered locally.

I installed the new Ubuntu 8.10 on friday. The thing
is I have no idea what the differences with the previous version are. So
let's take a look at the release notes and changelogs.
According to the changelog this new version of Ubuntu uses the new Gnome
2.24.
The release notes of Gnome
explain some of the new features.
The version of Gimp is also updated to 2.6. This new
version of Gimp has changed a whole lot.
Release notes are here.
I changed my font rendering to use Subpixel smoothing. I'm not sure. I
think I like it. The text on my screen looks a lot better now. It's
pretty.
Another big change is the user switcher. The user switcher is combined
with the shutdown button and your IM status. You can set your IM
status with the user switcher applet.
A lot of applications have been updated to new versions. Perl is now
version v5.10.0, which is the newest version. This version of perl has
a lot of nice new features,
including named captures, a switch statement, state variables, defined-or
operator and smart matching.
I had no problems with this update, except for mailman. That package was
only installed because I wanted to test it out for my production server.
But it seems the installation files have a problem because I did not have
any lists created, yet. This was not a big problem; I only had to run
sudo aptitude dist-upgrade.
All in all a nice and simple upgrade from 8.04 to 8.10, without any huge
problems.
