Automatic installation of missing packages isn't automatic when APT pulls multiple packages

[Loïc Minier]

Hi

Seen today while testing in a chroot:

Installing required command mkfs.vfat from package dosfstools
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
  dosfstools
0 upgraded, 1 newly installed, 0 to remove and 47 not upgraded.
Need to get 94.2kB of archives.
After this operation, 246kB of additional disk space will be used.
WARNING: The following packages cannot be authenticated!
  dosfstools
Authentication warning overridden.
Get:1 http://mirror.dooz.org/ubuntu/ maverick/main dosfstools amd64 3.0.9-1 [94.2kB]
[...]

=> installation was automatic (NB: authentication was overriden, not sure that's ok, might be local setup)

Installing required command qemu-arm-static from package qemu-kvm-extras-static
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following extra packages will be installed:
  qemu-user-static
Recommended packages:
  binfmt-support debootstrap
The following NEW packages will be installed:
  qemu-kvm-extras-static qemu-user-static
0 upgraded, 2 newly installed, 0 to remove and 47 not upgraded.
Need to get 11.5MB of archives.
After this operation, 30.3MB of additional disk space will be used.
Do you want to continue [Y/n]?

=> commands stops there; we seem to miss some APT flag to pull deps automatically

Cheers,

So for the record, this was withing a Launchpad buildd chroot which has 'APT::Get::AllowUnauthenticated "1";' in
/etc/apt/apt.conf.d/99buildd, hence the automatic installation of unauthenticated packages; it wouldn't install unauthenticated by default otherwise -- so no need for a separate bug for this part of the report.
