I’ve started getting the same thing in the last couple days. It happens on sudo apt update on the xenial workers.

As a temporary workaround you can do sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 762E3157.

To fix, I think travis will need to update its xenial image which is including the git-lfs repo.

Thanks for the report, I was going to do about the same as we are also affected.

We will do the workaround by adding the keyserver

This is still broken, but the workaround works!

Thanks for the report. Could you tell me how you identified the key ID?

#6

The key shows in the logs.

#7

You mean 6B05F25D762E3157?

#8

Yep. See the last 8 characters.

Workers using trusty are also affected on some builds, see:
https://travis-ci.org/Gallopsled/pwntools/jobs/482058694#L555
Is there any official status on this? Looks like it hasn’t been fixed yet.

Travis used do be amazing, but since a couple of years ago it started to went south,… and it seems only to accelerate in that direction.

#11

I’ve raised a support request relating to this as I don’t think the workaround is viable when using:

addons:
 apt:
  packages:
   - somepackage

If you know otherwise I’m happy to be wrong.

#12

Working on a fix…

#13

Where does that workaround go in the .travis.yml?

Mine looks like: https://github.com/django-tastypie/django-tastypie/blob/master/.travis.yml

Edit: Figured this out. Anybody else trying to use this workaround, add this section to .travis.yml:

before_install:
  - sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 762E3157

Also, this is pretty gross, and I hope they fix the xenial environment soon, given that it’s now the default environment for linux…

ISTM the real workaround is to use a newer Ubuntu image that does not suffer from this issue. Add to your .travis.yml:

dist: xenial

Xenial is already the default Ubuntu image. It’s been that way for a month or so.
