Oracle XE Database on Debian amd64

Question

Oracle

Greetings!
Trying to install Oracle DB from repository https://oss.oracle.com/debian
Stuck on trying to update the list of repositories, swears.

Err http://oss.oracle.com unstable/main i386 Packages                           
  302  Found
Err http://oss.oracle.com unstable/non-free i386 Packages                       
  302  Found

W: Failed to fetch http://oss.oracle.com/debian/dists/unstable/main/binary-i386/Packages: 302  Found
W: Failed to fetch http://oss.oracle.com/debian/dists/unstable/non-free/binary-i386/Packages: 302  Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
E: Couldn't rebuild package cache

As I understand it, it swears at the unavailability of packages for my architecture. The next command did not give a rezalta command.
dpkg --add-architecture i386
sources.list
