Hi,
Last few days apt-get turned to be very slow on my home desktop, with apt progress indicator showing 10-15KB/sec download speeds, occasionally dropping below 10KB/sec. This does not depend on particular mirrors used; also, access to 3rd party repositories hosted completely outside Canonical servers is equally slow. What is wierd, at the same time iftop confirms apt-get is actually utilizing most of the connection bandwidth (it is Verizon DSL, 5Mbit/sec D/L speed) and the transfer rates from servers are in the 300-600 KB/sec range, which looks like normal speeds. It is as if apt-get drops every 9 packets out of 10 received into a black hole. There is no errors whatsoever in any of the logs and dropped packets / errors counts for the network interface all stay at zero (ifconfig).
I have already spent several hours trying to debug and fix the problem, to no avail. Tried everything from disabling IPv6 in the kernel to power-cycling my DSL modem and NetGear router, none of my attempts had any effect on the apt-get download speed.
Muon and synaptic package managers are equally affected but all other programs' connection and download speeds seem normal (that is, fast as usual).
Did anyone else experience anything like that?
