'/home/omero/omero_dist/var/lib' was missing, and it's clearly there on 
both the installation and upgrade pages. Sorry.

I still had to correct ownership for /var/tmp/django_cache (apache) but 
once done it works.

Strangely, erroneous logins give this msg:

Error: Client version does not match server, please contact administrator.

which baffled me at first. Apologies if this has already been pointed out.

Thanks for your help,
