Forum OpenACS Q&A: Re: openacs seems to install successful.but still have problem about load lib.

how did you install OpenACS? did you compile everything yourself, or did you use a packaged version?
I using ubuntu12.04 and install by apt-get,process are:
0. apt-get update
1. apt-get install postgresql
2. apt-get install openacs
hmm, i have no ubuntu to check whether the install still does what it used to do.

Make sure,
- that apt-get did install the package aolserver4-nspostgres
- that postgres is up and running when you start openacs (postmaster should be listening on port 5432 in the default configuration)

i remember reports, that there was a timing problem for first debian/ubuntu installs, where openacs was starting before postgres was up and running. See e.g. end of thread http://openacs.org/forums/message-view?message_id=138993
