The problem consists in the following.
Installation passes normally until apt-setup does not try to get access to a mirror from which before necessary software packages have been loaded and installed. Here a photo of the console:
Installer says, that there is no communication with a mirror -
could not connect to ftp.de.debian.org:80 (1.0.0.0). Before it on the screen appeared the message on impossibility to connect to security.debian.org for reception of updates.
Tried to reinstall some times, to change mirrors - problems arise in the same places. Access to the network is organized through switch to which it is connected adsl modem d-link 500t.
At installation of Ubuntu there is a same problem.
The network and an Internet work normally - OpenSuse 10.3 perfectly works. In Internet has found the message on a similar problem at updating of Debian on a platform x86, a problem also it is not solved.
Your opinions under the decision of the given problem.
