Subject: It works, mostly.
So… I’m running Xubuntu 8.04 64 bit. Did a fresh install because we’ve been trying to get Notes 8.01 working on 64 bit systems in general.
You do need some 32bit libs.
ia32-libs is a must.
I also got some direction from this guy:

But I can streamline it a little for the Ubuntu people…
Definitely get the “getlibs” package. It’s handy. This is the list of libraries that you need to pass to getlibs (there is only one more that from the link above)
libavahi-client3
libavahi-common3
libavahi-glib1
libbonoboui2-0
libcroco3
libdbus-1-3
libdbus-glib-1-2
libeel2-2
libgnome2-0
libgnomecanvas2-0
libgnome-desktop-2
libgnome-keyring0
libgnome-menu2
libgnomeprint2.2-0
libgnomeprintui2.2-0
libgnomeui-0
libgnomevfs2-0
libgsf-1-114
libgsf-1-dev
librsvg2-2
librsvg2-common
libselinux1
libsepol1
libstartup-notification0
libxkbfile1
libXss
Or… just run this…
sudo getlibs -p libavahi-client3 libavahi-common3 libavahi-glib1 libbonoboui2-0 libcroco3 libdbus-1-3 libdbus-glib-1-2 libeel2-2 libgnome2-0 libgnomecanvas2-0 libgnome-desktop-2 libgnome-keyring0 libgnome-menu2 libgnomeprint2.2-0 libgnomeprintui2.2-0 libgnomeui-0 libgnomevfs2-0 libgsf-1-114 libgsf-1-dev librsvg2-2 librsvg2-common libselinux1 libsepol1 libstartup-notification0 libxkbfile1 libXss
For me… after a fresh Xubuntu 8.04 64 install I did the above and the gui installer works.
I still had to do the chown stuff on /etc/lotus and /opt/ibm … and I actually forget what I had to do with my ~/lotus directory… but it’s good.
Also, there seem to be some common issues floating around with the embedded swt browser not working quite right. Lots of suggestions about MOZZILLA_FIVE_HOME and so on. I simply modified my notes.ini to include this line:
BrowserRenderDisable=1
It is supposed to diable hthml rendering in messages, but it resulted in the errors going away and messages still rendering well. So that is confusing, but I like the results.
MY PROBLEM now… 
For some crazy reason I can’t open my workspace or anything in the “Open list”. BUT… I can open ALL of the databases that are IN my workspace and in my “Open list”.
What’s even more ridiculous is that I can right click on an “Application” in the open menu “Copy as link” paste it into a message, click on it, and it opens!!!
Anyway… it’s driving me crazy and I haven’t been able to figure out why it’s happening.
Wasn’t happening on my 7.10 system… but that system also had a lot more packages installed.
Also… the libfile.so thing as mentioned in above link is an issue. But, I think I can modify a 32 bit version of libgnome-vfs… to check the right location.
