I too have an Ubunru 8.04 derivate but I have sucessfully installed Wine 1.0. My install uses libldap-2.4.2 and that is what the dependencies tell me it needs. Which Ubuntu deriviate do you have (I have Kubuntu, Mythbuntu and Xubuntu but not plain Ubuntu) ? Which package manager are you using ? (adept, synaptic, plain apt ?). First try the sudo apt-get update step again - past the command into a console window and try installing wine again. Check that it is trying to install Wine 1.0 and not the older 0.9.59 from the Ubuntu repositories. If that still fails, report back with the output of ls -lR /etc/apt and cat /etc/apt/sources.list.d/winehq.list
