# > It happened to me and it turned out that I removed erroneously the postgres user from "ssl-cert" group, set it back with
gpasswd -a postgres ssl-cert

# Fixed ownership and mode
sudo chown root:ssl-cert  /etc/ssl/private/ssl-cert-snakeoil.key
sudo chmod 740 /etc/ssl/private/ssl-cert-snakeoil.key

# now postgresql starts! (and install command doesn't fail anymore)
sudo /etc/init.d/postgresql start
