The bugscript would have asked you for your configuration, so I am going to do it now instead: "apt-config dump". The message itself comes (or at least should) in response to Dir::Cache::pkgcache and Dir::Cache::srcpkgcache being empty and if the cache is forbidden to be build entirely in memory – which is the case for apt running as root for, well, reasons. I guess we should drop this, even through keeping everything in memory can be very slow… (I will have to recheck tomorrow if I haven't changed the semantics with my recent rewrite of the cache building. What I said is what happen in /experimental currently, I might have messed up the semantics…) You could try "-o Debug::NoLocking=1" btw, which should cause even root to use an entirely memory based cache. It does disable all locking through, so avoid running multiple apt/dpkg instances in the meantime… Best regards David Kalnischkies
