I may have missed this in the docs somewhere, but I found the instructions for the symlink at http://open-ils.org/dokuwiki/doku.php?id=server:1.2:ubuntu804:readme should be cd /openils/var/web/xul sudo ln -sf rel_1_4_0_0 rel_1_2_3_1 instead of cd /openils/var/web/xul sudo ln -sf rel_1_2_3_0 rel_1_2_3_1
