libegl-mesa0-dbgsym missing for focal-updates

[faecoin]

After some digging around, it seems to me that libegl-mesa0-dbgsym is generated but not available through ddeb server:

# apt-cache policy libegl-mesa0
libegl-mesa0:
  Installé : 21.2.6-0ubuntu0.1~20.04.2
  Candidat : 21.2.6-0ubuntu0.1~20.04.2
 Table de version :
 *** 21.2.6-0ubuntu0.1~20.04.2 500

# apt-cache policy libegl-mesa0-dbgsym
libegl-mesa0-dbgsym:
  Installé : (aucun)
  Candidat : 20.0.4-2ubuntu1
 Table de version :
     20.0.4-2ubuntu1 500
        500 http://ddebs.ubuntu.com focal/main amd64 Packages

Which explain why installation fail:
# LANG=C apt install libegl-mesa0-dbgsym
The following packages have unmet dependencies:
 libegl-mesa0-dbgsym : Depends: libegl-mesa0 (= 20.0.4-2ubuntu1) but 21.2.6-0ubuntu0.1~20.04.2 is to be installed

No dbgsym variant suffixed 21.2.6-0ubuntu0.1~20.04.2 is available from http://ddebs.ubuntu.com/ubuntu/pool/main/m/mesa/
(not sure if this would be the right URL for focal-updates ?)

But checking at https://launchpad.net/ubuntu/focal/+package/libegl-mesa0-dbgsym , it's has been built:
  https://launchpad.net/ubuntu/focal/amd64/libegl-mesa0-dbgsym/21.2.6-0ubuntu0.1~20.04.2

Is this only a ddeb synchronization error, which seem to happen from time to time for various reason? Or am I missing something else? Should this be filed elsewhere?
