After another test it seems that "apt-get download" doesn't use an advantage from the caches (partial and non-partial) as this example shows:

Or maybe "apt-get download" could be enhanced to use advantages of the caches and fallback to use no cache if something went wrong. -- 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/1425662 Title: "apt-get download" fails if /var/cache/apt/archives/partial is not accessible Status in apt package in Ubuntu: New Bug description: I'm using Ubuntu 15.04 dev with apt 1.0.9.3ubuntu1 and if /var/cache/apt/archives/partial is not accessible "apt-get download" doesn't download the requested package.
