Upgrading to a New Ubuntu LTS Release
If you SSH into an Ubuntu 18.04 LTS server, you might see a message that encourages you to simply run a command to upgrade to 20.04 LTS:
We strongly recommend against upgrading any server with a command like this for a few reasons. However, we can recommend the following options.
Option 1: Start Fresh
Instead of upgrading your server, we strongly recommend spinning up a fresh new server and copying your sites over to it. This allows you to test that a site works on the new server before flipping the switch on your DNS and sending traffic to it.
Yes, I know, it’s tedious and time-consuming to move a site to another server but SpinupWP makes it much easier with the Move Site feature.
Option 2: Ubuntu Pro
You could subscribe to Ubuntu Pro to get Extended Security Maintenance (ESM) releases.
Option 3: Stay on Ubuntu 20.04 or 22.04
If you’re on Ubuntu 20.04 LTS or 22.04 LTS, they will continue to receive security updates until April 2025 and April 2027 respectively, so it’s completely fine to continue running either for now. If you’re on 18.04 LTS, you should go with Option 1 or 2 above.
We’ll definitely give you a gentle nudge in the future if you’re still running a version of Ubuntu that’s approaching end of life (EOL), followed by a far less gentle nudge if you haven’t upgraded by the EOL date. 🙂
