I've tried to install for first time Lotus Notes 8.5.3 on Ubuntu 12.10 32bit , in a fresh installation over a laptop and the experience was great than i had expected.
This is the deb i've installed
All with Ubuntu Software Center
At the first run i've see the usually problem with search in this view, so i've used this library
wget http://www.benkevan.com/upload/lotus_notes/libgdk-x11-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgdk_pixbuf-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgdk_pixbuf_xlib-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgtk-x11-2.0.so.0 sudo mv *. so.0 /opt/ibm/lotus/notes
Another old problem with old solution with email attachement , when you click open, nothing happens
To solve this problem
sudo mv /opt/ibm/lotus/notes/openwith /opt/ibm/lotus/notes/openwith.bak sudo ln -s /usr/bin/gnome-open /opt/ibm/lotus/notes/openwith
