not valid XHTML

[JOZJAN.net]

www.ubuntulinux.org has nice XTHML icon at the bottom of page but W3C said
it's not vaid XHTML :

http://validator.w3.org/check?uri=http%3A%2F%2Fwww.ubuntulinux.org%2Fwiki%2F
UbuntuBootupHowto

This page is not Valid XHTML 1.0 Transitional!
Line 400, column 4: end tag for "ul" which is not finished
</ul>
...


BTW: Ubuntu rocks! But I am a litle sicked about curent mono
(www.go-mono.com) state at Ubuntu. I need mono 'cause I have to develop
asp.net pages and I don't want to install comercial Suse (or RedHat) or
migrate to Gentoo
(http://packages.gentoo.org/packages/?category=dev-dotnet).
