Prompt=normal

I've tried the obvious (apt update, apt upgrade, apt full-upgrade etc).

The problem was that the following packages were due to be updated:

➜  ~ sudo apt list --upgradable
Listing... Done
opendistro-alerting/stable 1.0.0.0-1 amd64 [upgradable from: 0.9.0.0-1]
opendistro-performance-analyzer/stable 1.0.0.0-1 amd64 [upgradable from: 0.9.0.0-1]
opendistro-security/stable 1.0.0.1-1 amd64 [upgradable from: 0.9.0.0-0]
opendistro-sql/stable 1.0.0.0-1 amd64 [upgradable from: 0.9.0.0-1]
opendistroforelasticsearch/stable 1.0.1-1 amd64 [upgradable from: 0.9.0-1]

Unfortunately, this could not happen in practice:

➜  ~ sudo apt install opendistro-alerting/stable
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Selected version '1.0.0.0-1' (. stable:stable [amd64]) for 'opendistro-alerting'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 opendistro-alerting : Depends: elasticsearch-oss (= 7.0.1) but 6.7.1 is to be installed
E: Unable to correct problems, you have held broken packages.

I temporarily removed elasticsearch-oss and the opendistro- packages, and then do-release-upgrade worked as expected.

    Well done! +1 for discovering apt list --upgradable. If I could give you a second +1 for the very sensible action of uninstalling the conflicting packages, I would. – user535733 Jul 15 '19 at 14:35

ubuntu 18.04 to ubuntu 19.04 is not a suported upgrade path

...that being said you can follow this guide:

https://www.linuxbabe.com/ubuntu/upgrade-ubuntu-18-04-to-ubuntu-19-04-directly-from-command-line

extract from the guide :

sudo apt update && sudo apt dist-upgrade
sudo apt install update-manager-core
sudo sed -i "s/Prompt=.*/Prompt=normal/g" /etc/update-manager/release-upgrades
sudo sed -i 's/bionic/disco/g' /etc/apt/sources.list
sudo sed -i 's/^/#/' /etc/apt/sources.list.d/*.list
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt autoremove
sudo apt clean
