Dear all,
Please CC me while answering as I'm not subscribed to the list, sorry.
I was looking at the output of $ apt-key list
and saw the following -
$ apt-key list

It actually had slightly different values for the jessie and strech
keys (dates) which I deleted and then found I could not use apt update
as it gave errors such as -
The following signatures couldn't be verified because the public key
is not available: NO_PUBKEY 7638D0442B90D010 NO_PUBKEY
04EE7237B7D453EC
The following signatures couldn't be verified because the public key

Then I searched and saw a forum post sharing that the
debian-archive-keyring is maybe not up-to-date.
I downloaded the latest from sid/unstable and using dpkg -I did the
installation although the latest would have migrated to buster
tomorrow itself according to tracker.debian.org/debian-archive-keyring
.
$ wget
http://ftp.de.debian.org/debian/pool/main/d/debian-archive-keyring/debian-archive-keyring_2019.1_all.deb
$ sudo dpkg -i debain-archive-keyring<TAB> for auto-completion
So now it showed -
$ apt-cache policy debian-archive-keyring
debian-archive-keyring:
Installed: 2019.1
Candidate: 2019.1
Version table:
*** 2019.1 500

100 /var/lib/dpkg/status
2018.1 990
990 http://cdn-fastly.deb.debian.org/debian buster/main amd64 Packages
did that and tried again but still got the same errors as above.
Then I did -
root@debian:~# gpg --recv-keys 04EE7237B7D453EC
gpg: key E0B11894F66AEC98: 12 signatures not checked due to missing keys
gpg: /root/.gnupg/trustdb.gpg: trustdb created

gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1
root@debian:~# gpg --export 04EE7237B7D453EC | apt-key add -
OK
I still got errors but less errors hence did the same procedure as above -
$ su -
Password:
root@debian:~# gpg --recv-keys 9D6D8F6BC857C906
gpg: key 9D6D8F6BC857C906: 13 signatures not checked due to missing keys

gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1
root@debian:~# gpg --export 9D6D8F6BC857C906 | apt-key add -
OK
now when I looked at apt-key list I see these two -
pub rsa4096 2017-05-22 [SC] [expires: 2025-05-20]

I found it odd that the jessie and the stretch keys are and were being
used and couldn't understand why.
I also looked at the list of files in the package -
$ dpkg -L debian-archive-keyring
/.

Find it strange that stretch and jessie keys are being used. Perhaps
for migration purposes from jessie or stretch to buster ?
I also saw the documentation
~$ cat /usr/share/doc/debian-archive-keyring/README
but it didn't tell me much that I didn't already know.
If I'm reading right, some 2.5 years from now, jessie will be dropped
but only stretch will remain if I'm on buster otherwise, if I'm on
bullseye, the new release then (i.e. bullseye) would have keys of
bullseye, buster and stretch.
Is that the way things work or am I missing, misunderstanding something ?
