apt does what it is told – appstream configures apt to download only the files for the native architecture, so there is no sensible action to be taken by apt and hence this task invalid.
If "$(NATIVE_ARCHITECTURE)" in the apt.conf file shipped by appstream is changed to "$(ARCHITECTURE)" apt will download the files for all configured architectures – if that is really desired is what appstream developers have to figure out. I will add that it might be also a good idea to add support for Components-all first to avoid at least a bit of duplication (yes, apt supports downloading those files, too, it just wont by default – but that default can be switched via Release file metadata). ** Changed in: apt (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1718453 Title: apt does not download dep11 files for foreign architectures and appstream cannot find applications for these archs.
