Unnecessary Warning About Ubuntu 24.04 Image Changes in Azure DevOps Pipelines

[ashokm]

Description

When using the ubuntu-24.04 image in Azure DevOps, an unnecessary warning is displayed in pipeline logs:

##[warning]See https://aka.ms/azdo-ubuntu-24.04 for changes to the ubuntu-24.04 image. Some tools (e.g. Mono, NuGet, Terraform) are not available on the image. Therefore some tasks do not run or have reduced functionality.

This warning appears even when we explicitly choose ubuntu-24.04 and do not require any of the removed tools. It creates unnecessary noise in logs and cannot be suppressed, making it an annoyance for teams who have already accounted for the image changes.

Would appreciate any input on whether this warning can be removed or made optional. When a pipeline has many jobs, this warning is shown multiple times, adding significant noise to the logs and making it harder to focus on important information.

Is it regression?

N/A

Expected behavior

• If users explicitly select ubuntu-24.04, this warning should not be shown.
• There should be an option to suppress or disable this warning in Azure DevOps.

Actual behavior

• The warning is always displayed, even when it's not relevant.
• There is no way to turn it off.

Repro steps

1. Set up an Azure DevOps pipeline with:

   trigger:
   - main
   
   pool:
     vmImage: ubuntu-24.04
   
   steps:
     - script: echo "Hello World"
   

2. Run the pipeline and observe the warning message in the logs.

Hi @ashokm, Thank you for bringing this issue to our attention. We are looking into this issue and will update you on this issue after investigating.

[vidyasagarnimmagaddi]

Hi @ashokm , we have informed this to the concerned team, Hopefully issue will be resolved. kindly await. regards

[HoteaCatalin]

Hi, this is also applying when using ubuntu-latest, and I think it should not display this warning.

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:
  - script: echo "Hello World"

[DergachevE]

Hi @HoteaCatalin ,
For Azure DevOps tag ubuntu-latest this warning is valid as it points to Ubuntu 22.04:
https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&tabs=yaml#software

So this banner notifies customer that soon this tag will point Ubuntu 24.04 with mentioned changes in tools

Is there any way to suppress this warning? It also appears when running on ubuntu 22.04 in our privately hosted agents (running the image built from this repo).

[damianobarbati]

How can we suppress this message? It's pretty annoying.

[vidyasagarnimmagaddi]

Hi @ManagedUx ,@damianobarbati , We are in progress of suppressing the warnings , We will be informing you soon.thanks

[mikefromgrr]

Hi @ManagedUx ,@damianobarbati , We will be reverting you for suppressing the warning .thanks

Good luck guys. I'd hate to be reverted. 😀 I must have lost something in translation.

We are in progress of suppressing the warnings , We will be informing you soon.thanks

Any update on this? The warning is still showing up in the logs, and clutters the pipeline overview page with unnecessary warnings.

Thanks!

[thewellington]

inquiring minds want to know....

[vidyasagarnimmagaddi]

Hi all, The warnings would be removed by next week . Kindly await. thanks

[deepak-techi]

Is this warnings removed ?

[deepak-techi]

@vidyasagarnimmagaddi - I am also facing the same warning issue: "https://aka.ms/azdo-ubuntu-24.04 for changes to the ubuntu-24.04 image. Some tools (e.g. Mono, NuGet, Terraform) are not available on the image. Therefore some tasks do not run or have reduced functionality."

Have googled it to find the workaround but no luck. please help.

[rexhinok]

using ubuntu-latest as a vmImage and still get this warning.
"Therefore some tasks do not run or have reduced functionality." is ambiguous

[vidyasagarnimmagaddi]

Hi @ashokm , Warnings have been suppressed, could you please check once and confirm . thanks.

[CaringDev]

Hi @ashokm , Warnings have been suppressed, could you please check once and confirm . thanks.

With vmImage: ubuntu-24.04 I still get

##[warning]See https://aka.ms/azdo-ubuntu-24.04 for changes to the ubuntu-24.04 image. Some tools (e.g. Mono, NuGet, Terraform) are not available on the image. Therefore some tasks do not run or have reduced functionality.

[thewellington]

I still get the warnings too. I thought these were being turned off a week or more ago. Evidently not

[vidyasagarnimmagaddi]

Hi @thewellington ,the activity is being rolled out , kindly await for the roll out to be completed fully. regards

[Nilsas]

Do we have any ETA on when will the rollout be completed?

Just checked - warnings continue.

[mdsharpe]

Warnings still there. Still annoying.

[thewellington]

Still have warnings today. @ashokm can we get an ETA on when this should be rolled out to all customers?

[ashokm]

@vidyasagarnimmagaddi , apologies for the late reply to your message.

I retested this today using the same reproduction steps, and unfortunately, the issue still persists.

Here's an excerpt from the latest build output:

[dirkluijk]

It's really intrusive. Annoys me now for several weeks, every moment of the day... (this is also me complaining about the UX of Azure Devops).

[ManagedUx]

ve been suppressed, could you please check once and confirm . thanks.

Can confirm, still showing up on our privately hosted pools as well.

So this banner notifies customer that soon this tag will point Ubuntu 24.04 with mentioned changes in tools

Since the banner does not say that, no, this banner does not

[vidyasagarnimmagaddi]

Hi @ashokm and all, We can confirm that the activity is completed. Could you please verify at your end .

Note:We have removed the warning for pipelines that use ubuntu-24.04 explicitly, but not yet for ubuntu-latest
Customers would still receive the warnings if they use some tasks in ubnutu-24.04

[pbering]

@vidyasagarnimmagaddi confirming that it is gone here (using ubuntu-latest)

[CaringDev]

Given

Note:We have removed the warning for pipelines that use ubuntu-24.04 explicitly, but not yet for ubuntu-latest
Customers would still receive the warnings if they use some tasks in ubnutu-24.04

I'm surprised that it is gone for both ubuntu-24.04 (me) and ubuntu-latest (@pbering )... however, I don't mind, quite the opposite :-)

[ashokm]

Hi @vidyasagarnimmagaddi, I can confirm that the warning is no longer appearing when using the same reproduction steps.
