I'm trying to install postgresql as root using vagrant on a lucid32 box:

add-apt-repository ppa:pitti/postgresql
apt-get -y update
apt-get -y install postgresql libpq-dev

Installation proceeds fine until:

Setting up postgresql-9.1 (9.1.3-1~lucid) ...
Creating new cluster (configuration: /etc/postgresql/9.1/main, data: /var/lib/postgresql/9.1/main)...
initdb: encoding mismatch
The encoding you selected (UTF8) and the encoding that the
selected locale uses (LATIN1) do not match.  This would lead to
misbehavior in various character string processing functions.
Rerun initdb and either do not specify an encoding explicitly,
or choose a matching combination.
Error: initdb failed
Error: could not create default cluster. Please create it manually with

  pg_createcluster 9.1 main --start

or a similar command (see 'man pg_createcluster').
update-alternatives: using /usr/share/postgresql/9.1/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode.

Setting up postgresql (9.1+128~lucid) ...
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place

Then when I try to enter postgres, I get this error:

root@lucid32:~# sudo -u postgres psql
could not change directory to "/root"
psql: could not connect to server: No such file or directory
	Is the server running locally and accepting
	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

Any help?
