Is it possible to upgrade Ubuntu from 16.04 to 18.04?
Are there any known issues with upgrading from 16.04 to 18.04 so far?
What precautions can I take to minimize the potential for data loss and down time? And how do I start the update?
Thank you in advance

Clone your Ubuntu and upgrade the clone. Do it many times if necessary until all kinks worked out: askubuntu.com/q/1028604/307523

Yes it is possible to upgrade 16.04 to 18.04. The list of known issues is too long to post in an answer. Key "18.04" in the search bar above and you will find many hours of reading. The precautions to take are listed in my answer below. You start the upgrade withdo-release-upgrade -dbut as in my answer below do this on a cloned copy of Ubuntu 16.04.

When in doubt err on the side of caution. The best thing to do is test, test and test some more. Using this script: Bash script to clone Ubuntu to new partition for testing 18.04 LTS upgrade you can clone your Ubuntu 16.04 to a new partition and run the upgrade to 18.04 on the new partition.
If the upgrade fails, find out why, wait for fix, clone the data again and rerun the upgrade.
After the upgrade succeeds test each application you use. If one doesn't work, find out why, wait for fix, clone the data again and rerun the upgrade.
The other part about testing is to choose which of the five unique signons you like best between Gnome, Unity, Wayland, X11 and combinations therein.
Additionally you can install new applications previously not available such as tweak tools and experiment with them. If you break something, clone the data again and rerun the upgrade.
Wash, Rinse, Repeat then Repeat again...

A safer alternative is to make a fresh installation, but keep the /home directory as a separate partition and select it (without formatting) via 'Something else' at the partitioning window in the installer.

I did the upgrade last Saturday and Sunday (27 Apr 2018) on my desktop and laptop. Here are the issues I faced:
My desktop froze during the upgrade (from the Internet) and I had to do a full re-upgrade from CD. Following this I was unable to launch a terminal for manual command, so I re-installed the whole thing, and it is running fine since. Desktop is running AMD Phenom IIx4, with 12Gb memory.
My laptop upgrade was more successful: kept all my files system, but the Ethernet connection isn't recognized anymore (I can access Internet through Wi-Fi only), despite the updates made on 30 Apr 18 (see: Unable to connect with Ethernet under 18.04). Laptop is running Intel Core2 T9800 CPU, with 8Gb memory.

"As far as I know, there are no risks whatsoever." a ludicrous comment if there ever is one. Change means risk, always. Sometime a lot some times not. Risk increases with complexity, but you can always mitigate it. How far you go depends on the cost of loss if it all screws up. 1st of all backup/clone/replicate. If its a production system duplicate it and play with the upgrade on the duplicate...

As far as I know, there are no risks whatsoever. Canonical even states that it's safe. They did say that it would be easier, however, to simply reinstall the OS later on than upgrading. Here's a link to their guide on upgrading to another version (NOTE: it didn't work on my install, but I didn't have a good, reliable internet connection).

"As far as I know, there are no risks whatsoever." a ludicrous comment if there ever is one. Change means risk, always. Sometime a lot some times not. Risk increases with complexity, but you can always mitigate it. How far you go depends on the cost of loss if it all screws up. 1st of all backup/clone/replicate. If its a production system duplicate it and play with the upgrade on the duplicate...

As far as I know, there are no risks whatsoever. Canonical even states that it's safe. They did say that it would be easier, however, to simply reinstall the OS later on than upgrading. Here's a link to their guide on upgrading to another version (NOTE: it didn't work on my install, but I didn't have a good, reliable internet connection).

There are lots of risks. Key "18.04" into search bar. Sort the results by date and you'll see many problems every hour.

Clone your Ubuntu and upgrade the clone. Do it many times if necessary until all kinks worked out: askubuntu.com/q/1028604/307523

Yes it is possible to upgrade 16.04 to 18.04. The list of known issues is too long to post in an answer. Key "18.04" in the search bar above and you will find many hours of reading. The precautions to take are listed in my answer below. You start the upgrade with
do-release-upgrade -dbut as in my answer below do this on a cloned copy of Ubuntu 16.04.– WinEunuuchs2Unix
