@danackerson Thanks for the feedback! Could you share the exact commands that you ran, or your config.yml? I was not able to reproduce the problems with this simple config:

version: 2.1
jobs:
  build:
    machine:
      image: ubuntu-1604:202004-01
    steps:
      - checkout
      - run: sudo apt-get update
      - run: sudo apt-get upgrade
workflows:
  version: 2
  build-and-deploy:
    jobs:
      - build

Well, this is embarassing but I used

sudo apt update

After changing this to the recommended

sudo apt-get update

all clear!

Thanks again :slight_smile:

We updated from the previous image because apt update failed there, as well.
And now the fresh image has broken repos from the start?

I don’t see how using apt-get is a solution.

Could you retest this? @stella

It’s definitely broken for sudo apt update (for us).

Thanks

@valentinsavenko Thank you for the feedback. This issue was something overlooked during the update of the image and we’re currently investigating it. In the meantime, we recommend using sudo apt-get update if it meets your needs.

I’ve been using ubuntu-1604:202004-01 and I worked around the apt update issue by adding rm /etc/apt/sources.list.d/circleci_trusty.list before updating apt. Now my builds are failing with rm: cannot remove '/etc/apt/sources.list.d/circleci_trusty.list': No such file or directory so I have to revert that change.

Did the machine image change without the tag changing?

This image has been patched to fix the apt update issue.

If you use apt-get, you don’t get a failed build do to this issue.

Yes, it was patched. Your workaround is no longer needed.

In the future, could you please bump the tag instead of pushing a new image to the same tag? This broke CI in a half-dozen repos for me. I’d happily remove the workaround and switch to a ubuntu-1604:202004-02 tag, but it’s not fun when I have to drop what I’m doing and fix this immediately.

@ggreer We had hoped it would be a fix transparent to existing users; apologies for the disruption caused and thank you for the valuable feedback.

11

Definitely a no-go to release a shadowed patch underneath the hood. Nobody does expect this kind of behaviour when running their daily CI’s.

How can someone even rely upon having deterministic builds for their products if patches are shipped silently. Additionally it makes debugging even harder if something accidently go wrong for pipeline execution.

12

The patch system that we have in place is for the very scenario, to fix an image that shipped broken. We ship new releases when software is simply being updated.

The workaround we suggested to users (using apt-get instead of apt) who reported and experienced this problem didn’t cause the image to break once we fixed the problem. We can’t predict users doing something outside of what we suggest.

While I understand what happened for you @ggreer, I’d ask that you also understand we had support tickets with users asking for us to fix this problem the way did, with pushing this patch. They would have been upset if we forced them to use another tag for the image instead of just fixing it. We’re doing our best to please as many people as we can.

Lastly, I do want to share that the responsibility for the Linux machine image is moving to another team at CircleCI as we speak. What we’re hoping to deliver with this change is more TLC for the Linux machine image. We’re looking to deliver more frequent, scheduled updates, improved community on changes (including ahead of time communication), faster updating Docs when this images changes, etc.

I’ll make sure to discuss with the new team our existing patch process as it is today, and see if there’s a way we can improve it. Our team also works on the Convenience Images (Docker) and if you’ve heard anything about the next-gen images, we specially don’t touch existing image tags as a default practice. Perhaps we do the same here. Stay tuned to this Announcements category and the CircleCI Discuss Images category for future information on this.

I would just like to echo @ggreer that I don’t find it acceptable to make machine image changes under the same tag in a CI/CD system such as this. It is very surprising that an image tagged with a date and number would change under the same tag. Everything should remain identical unless the user chooses to make a change, or opted into a dynamically updating environment. The security implications of this within a secure SDLC are worth considering as well…
