Ubuntu upgrade from 16.04 to 18.04 in AWS EC2

rated 0 times [ 10] [ 0] / answers: 1 / hits: 10383 / 1 Year ago, mon, december 19, 2022, 12:15:12

My AWS EC2 instance is running on Ubuntu 16.04. But recently I got an email from AWS that Canonical - the company that provides the support of Ubuntu 16.04 LTS - will stop its support on April 30, 2021.

So should I upgrade my instance to Ubuntu 18.04 or let my server run on 16.04. Will this upgrade affect my software and customers?

A little confused, please help!

So should I upgrade this to Ubuntu 18.04

No. NEVER EVER upgrade a cloud instance. NEVER. Remember: ssh access is the only access you have. If that breaks your instance is gone and you depend on backups and a new instance to get back up running. It is not worth the risk.

or let my server run in 16.04.

Yes. And is is not a server, it is a cloud instance.

You have 2 disks, and if you do not fix your instance by separating system and personal files.

So ...

a system disk holding 16.04

a personal disk holding all your data.

The correct procedure:

detach your personal partition from the 16.04 instance

create a copy of your personal disk

create a new instance using 18.04 or 20.04

attach the copy to this new instance

boot and fix issues regarding software you have installed. Apache is normally not a problem. MySQL in 20.04 will have issues: 20.04 uses MySQL 8 so things changed. You can however install 5.6/5.7 if you want and use that.
