nginx (nginx-common) doesn't symlink sites-available/default back to sites-enabled/ unless it's a fresh install (no other version was either installed or in config-files state).
I actually tried using snapshot.debian.org to: o install nginx-common_1.2.4-2 o delete sites-enabled/default o upgrade to nginx-common_1.2.6-1 o No default symlink to sites-enabled/ was created So, maybe in your case: o default was already symlinked to sites-enabled/default o 1.2.6 upgraded the default config file (with a broken listen directive due to the ipv6 bug) o you ended up with a broken configuration -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
