I have the 64 bit version of Debian etch running on an AMD system. All
was well until recently when it stopped doing updates with the error:
cannot connect to host 4001: 127.0.0.1 connection refused (error 111 ...)
(Note that this as close as I can remember the error message as I
rebooted into ubuntu 32 bit before writing this)
It still connects to the internet and is happy to browse but if I ask it
to check for updates it gives this error and apt-get update also gives
this error on the repository I use.
Although now, since moving from SuSE, I usually use Ubuntu I am not
familiar with Debian. Is this a common error and is it easily fixed? Any
clues appreciated.
