Describe the problem

IT looks like the GPG key expired again (See previous issue: #1457)

sudo apt update
...
Ign:5 https://storage.googleapis.com/download.dartlang.org/linux/debian stable InRelease
Get:8 https://storage.googleapis.com/download.dartlang.org/linux/debian stable Release [944 B]

Ign:9 https://storage.googleapis.com/download.dartlang.org/linux/debian stable Release.gpg
...
Reading package lists... Done
W: GPG error: https://storage.googleapis.com/download.dartlang.org/linux/debian stable Release: The following signatures were invalid: BADSIG 4EB27DB2A3B88B8B Google Inc. (Linux Packages Signing Authority) [email protected]
E: The repository 'https://storage.googleapis.com/download.dartlang.org/linux/debian stable Release' is not signed.

Expected fix

Update the signing key / Re-sign the repository

Additional context

A Dockerfile with the following will not build:

FROM docker.sel.inc/ubuntu:20.04
# Install Dart
RUN apt-get update && apt-get install -y apt-transport-https \
    && sh -c 'wget --waitretry=5 -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -' \
    && sh -c 'wget --waitretry=5 -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'
RUN apt-get update && apt-get install -y dart=2.14.4-1

When running it locally, it is apparent that the apt-get update fails:

Reading package lists... Done

Thanks for opening an issue! Looks like this issue is being tracked on the SDK repository: dart-lang/sdk#53045

For now, I'll keep this open as well so users visiting this repo see it and in-case there's anything we need to change on dart.dev.

I'm going to close this issue as the SDK issue has been marked as fixed with some extra information: dart-lang/sdk#53045 (comment)

Thanks again for opening an issue and let us know if you have any further issues!
