About "Ubuntu 18.04 LTS end of standard support is 31 May 2023" email

Question

We become indebted to.

I received the following email from MS.

Looking at the subscription ID, it seems to be a product managed by our company.

I don't know that you are using Ubuntu Server.

Please check the following two points.

1. It says that this email was sent because I deployed, but which service should I take action on to receive the following email?
2. As far as the content of the email is concerned, the Ubuntu 18.04 server can still be used, but it can be received that security will not be guaranteed.

Do you understand that Ubuntu 18.04 will not be stopped even if you do not respond?

Ubuntu 18.04 LTS end of standard support is 31 May 2023—ensure your VMs are on a supported operating system

You're receiving this email because you've deployed Ubuntu 18.04 on Azure.

On 31 May 2023, Ubuntu 18.04 LTS will reach the end of standard support. After this date, you'll still be able to use your existing virtual machines, however, security, maintenance, and feature updates will no longer be provided by Canonical and your VMs may become vulnerable.

To avoid potential vulnerabilities, review the following options and choose the one that best fits your needs:

Upgrade to Ubuntu 20.04 LTS or Ubuntu 22.04 LTS, the latest operating systems which offer improved performance and hardware enablement.

Purchase Ubuntu Pro, which includes security patching for all Ubuntu packages. Ubuntu Pro 18.04 LTS will remain fully supported until April 2028.

Read more details about these options.

Recommended action

To ensure your VMs are running on a supported OS and can still receive security updates, upgrade Ubuntu or purchase Ubuntu Pro by 31 May 2023.

Answer 1

Hello 加賀崎 隼

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

Looks like you received an email from Microsoft regarding the end of standard support for Ubuntu 18.04 LTS on May 31, 2023. This email was sent to you because you have deployed Ubuntu 18.04 on Azure.

To answer your questions, the email does not specify which service you should take action on to receive the email. However, it is recommended that you upgrade to Ubuntu 20.04 LTS or Ubuntu 22.04 LTS, or purchase Ubuntu Pro to ensure that your VMs are running on a supported OS and can still receive security updates.

It is correct that Ubuntu 18.04 will not be stopped even if you do not respond. However, after May 31, 2023, security, maintenance, and feature updates will no longer be provided by Canonical, which may make your VMs vulnerable to potential security threats.
