    Install and configure Sendmail on Ubuntu
This should help you get Sendmail installed with basic configuration on Ubuntu.

If sendmail isn't installed, install it: sudo apt-get install sendmail
Configure /etc/hosts file: nano /etc/hosts
Make sure the line looks like this: 127.0.0.1    localhost yourhostname
Run Sendmail's config and answer 'Y' to everything: sudo sendmailconfig
Restart apache sudo service apache2 restart

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

Database files have to be updated before starting the server, here are the steps that had to be followed:

# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql

## elasticsearch 5.x on Dokku
All right, just a quick recap on this issue for people looking to setup Elasticsearch 5.x. There's a workable solution in the above comments, but was a bit of trial an error. Hope this speeds things up for others:

Edit /etc/sysctl.conf, add vm.max_map_count = 262144 at the bottom. Then run sysctl -p to load the changes.

Create a new Elasticsearch instance with dokku, per manual. I've only tested this with the latest 5.x release.

export ELASTICSEARCH_IMAGE="elasticsearch"
export ELASTICSEARCH_IMAGE_VERSION="5.6.12"
dokku elasticsearch:create lollipop
This will result in the "unable to connect" error. But now worries.
