Package: www.debian.org Severity: normal Hello,
looking at:
https://packages.debian.org/search?keywords=thunderbird&searchon=names&suite=stable§ion=all
this lists the thunderbird packages from buster, while bullseye is the
current stable release.
Probably related to that packages.d.o doesn't know about
bullseye-security and bullseye-backports.
Best regards
Uwe
