Hi @mstormi,
After considering the upgrade point, I have removed the milestone build from the snapshot repository. It is still available on the testing repository.
For everyone looking to get back on the daily snapshot builds, please use the following command to find the latest version:
sudo apt update
sudo apt-cache madison openhab2
The top version listed as a response will be the latest version (e.g. 2.4.0~20180827190222-1), and can be installed using:
sudo apt install openhab2=2.4.0~20180827190222-1
Apologies for the inconvenience!
