DigitalOcean Ubuntu 14 -> 16

Finally getting around to upgrading my DigitalOcean Ubutu LAMP droplet from Ubuntu 14 -> 16.

Steps:

1. BACKUP db (I forgot this step!!). Ideally copy db dump to local
2. Make a snapshot of droplet
3. sudo apt-get update
4. sudo apt-get upgrade
5. sudo apt-get install update-manager-core
6. sudo do-release-upgrade

 

For DigitalOcean it says not to worry about the SSH issue so just type ‘y’ through the rest of the prompts.

I ran into a bunch of strange ‘error’ messages and just ignored them and seemed like everything came out OK.  Hope it does for you too
