I am not sure if you can update Graylog with:

sudo apt-get install graylog-server

Graylog 5 has a lot of changes, it is better to follow the official guide on how to upgrade it. Graylog 5 requires a different mongo version.

You might can try:

wget https://packages.graylog2.org/repo/packages/graylog-5.0-repository_latest.deb
sudo dpkg -i graylog-5.0-repository_latest.deb
sudo apt-get update && sudo apt-get install graylog-server

If it is a test instance (throw away), maybe you can risk it without looking into the documentation, but if it is in any for a production environment, read more about the upgrade process.
There is a video with all steps and how to upgrade mongo first.

Second this…

It is not a simple upgrade… for instance if you are in a hyper-v environment, you may not be able to upgrade to MongoDB 5 and Graylog 5 docs state the Mongo 5 or 6 is required

Thanks everyone. This is still a test. Im within an ESXi environment but im backing up the VM so im ok to do the upgrade from that standpoint.
The problem was finding the documentation on upgrading.

edit - i have to RTFM.
needed to update my repo as instructed. Im good now.
