Forum OpenACS Development: Re: New Installation on Ubuntu 11.10
I can't comment on the ubuntu installation, but it seems to me as if you need the ubuntu packages aolserver4-nspostgres and aolserver4-nssha1. Does anyone know what happened with these? Is this maybe a question of Ubuntu versions?
Most likely, you do NOT need the mentioned patch, since this patches are included in versions of aolserver and naviserver since 4 or 5 years. Please include version numbers in you error reports. Use aolserver 4.5.1 or newer, and you are fine in this respect.
In case you need the patch, check the OpenACS wiki, you will find there: http://www.openacs.org/xowiki/Boost_your_application_performance_to_serve_large_files!
all the best
