I can confirm this issue on fontconfig-config 2.9.0-3 on up-to-date testing.
Exisiting id-cache file prevents other packages from updating (postinst files are not run). I definitely did not created that file manually. Besides, it has -cache in name, so perhaps it is safe to remove it, as it may be regenerated if anyone ever needs it (which is unlikely, as dafoma is in process of deprecation). -- Best regards Mirosław Zalewski -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
