I found CD images for the 18.10 beta, but I'm wondering if there is a way to upgrade OTA. I have the bionic-proposed box checked, but there is still nothing.
sudo apt update sudo apt upgrade sudo apt dist-upgrade sudo apt autoremove
Those will make sure your current system is up to date.
/etc/update-manager/release-upgrades and set
Prompt=normal to avoid the "No new release found message."
This will start the upgrade:
sudo do-release-upgrade -d
Big fat warnings:
- Please do not do this on a production server. 18.10 is not ready for general usage and breaking your system is more likely than having a working system. Every new update might break something.
- If you have personal data do make a backup every day and save them all. At some point you might need to re-install as every update could break your boot procedure. Knowing a little not more then average about the inner workings of Ubuntu so the base system, Linux, systemd, the boot process would be good to have.
- Biggest problem probably will be 3rd party drivers. I would remove them and stick to the open source versions when upgrading and re-enable them when there is a working newer system.
