Bullseye security.debian.org codename misconfigured?

[Stefan Fritsch <sf@sfritsch.de>]

Hi,

I have noticed that the latest linux security update is not installed on 
my box. The package is available in

# apt-cache policy linux-image-amd64
linux-image-amd64:
  Installed: 5.10.84-1
  Candidate: 5.10.84-1
  Version table:
     5.15.15-1 500
        500 http://mirror.hetzner.de/debian/packages unstable/main 
amd64 Packages
     5.10.92-1 500
        500 http://security.debian.org bullseye-security/main amd64 
Packages
 *** 5.10.84-1 990
        990 http://mirror.hetzner.de/debian/packages bullseye/main 
amd64 Packages
        100 /var/lib/dpkg/status


But apt-get dist-upgrade does not install it. I have

# cat /etc/apt/apt.conf.d/11-default-release
APT::Default-Release "bullseye";

and bullseye-security has

# grep -i code 
/var/lib/apt/lists/security.debian.org_dists_bullseye-security_InRelease
Codename: bullseye-security

while on buster, it's:

$ grep -i code 
/var/lib/apt/lists/security.debian.org_dists_buster_updates_InRelease
Codename: buster

No -security there.

I have no apt pinning configured on my box.

I think the bullseye-security codename should be "bullseye" instead. Or 
am I missing something

Cheers,
Stefan
