Hi there,
I have had a strange problem for some time now. I have installed Debian many times, it is absolutely my favourite. I used to install from the netinstall image, but since sometimes like half a year ago, in the end of the installation it could not find any file mirrors, and the installation could not be completed.
At the time I had a lot of problems with my LAN, and that clouded the problem for some time. Now I found the error, a defective patch cable, but even now, a installation from the netinstall image does not work. No matter what I do, it times out on adding the file mirrors.
I then downloaded a live CD with a desktop, there I selected to skip the file mirrors, and added them myself in sources.list from the wiki. That works, but now I have another problem: Every time I use wget to make a connection, it takes a looooong time before the connection is made. As soon as that happens, the connection goes at normal speed.
I am on a fast 250/250 fibre connection with a very low latency, so that should no be the problem.
My sources.list looks like this :
deb http://deb.debian.org/debian stretch main contrib non-free
deb-src http://deb.debian.org/debian stretch main contrib non-free
deb http://deb.debian.org/debian stretch-updates main contrib non-free
deb-src http://deb.debian.org/debian stretch-updates main contrib non-free
deb http://security.debian.org/debian-security/ stretch/updates main contrib non-free
deb-src http://security.debian.org/debian-security/ stretch/updates main contrib non-free
As you can see, I'm running Stretch, but I have had the very same problem with Jessie and Buster.
Cheers
Niels
