Bug Description

[Impact]

 * For LTS releases to be able to bootstrap dual and single signed future releases, and validate all signatures, 2018 archive signing key should be SRUed back

 * Also build process has improved documentation and vague validation that all key snippets are signed correctly

[Test Case]

 * $ apt-key list
...
/etc/apt/trusted.gpg.d/ubuntu-keyring-2018-archive.gpg
------------------------------------------------------

uid [ unknown] Ubuntu Archive Automatic Signing Key (2018) <email address hidden>
...

apt-key list should contain the 2018 archive key.

[Regression Potential]

 * Build-process, key algo, and key size, and file format are the same as previous key snippets thus supported by all of gpg1 gpg2 gpgv1 gpgv2.

[Other Info]

 * 2018 key is to be used for dual-signing in DD series and up

 * Bileto PPA is built against security pocket only, suitable to be released into both -security and -updates

Hello Dimitri, or anyone else affected,

Accepted ubuntu-keyring into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ubuntu-keyring/2018.09.18.1~18.04.0 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

It might be nice to provide this on older LTS releases too.

all is good for bionic. Prior releases should only probably ship this key in the ubuntu-keyring.gpg, but not as a trusted.gpg.d key snippet. As we do not anticipate to use 2018 key to sign the bionic archive.

This upload lists autopkgtest regressions for all arches for pbuilder - could you take a look if those are unrelated or not? Looks fishy, since some of those were passing fine just recently for other packages.

I will retrigger ubuntu-keyring adt of debootstrap, with debootstrap from bionic-proposed.

The other obvious regression potential (to me anyway) is that previously existing keys become missing. Could someone check for that please?
