openSUSE install links broken

[ozfossil]

Following the instructions and links on https://www.virtualbox.org/wiki/Linux_Downloads (OpenSUSE) section and it appears the links do not point to the appropriate files on your servers.

The following terminal output showing errors below:

peter@localhost:~> sudo rpm --import oracle_vbox.asc

[sudo] password for root: peter@localhost:~> wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | rpm --import - error: -: import read failed(0).

peter@localhost:~> zypper refresh

Root privileges are required to run this command.

peter@localhost:~> sudo zypper refresh

Another problem for noobs is the error in instruction missing the "sudo" root user authority - easy to correct this one as terminal gives the correct advice. ("instruction to run zypper refresh")

I cannot find any advice on how the following can be implemented "Users of openSUSE can add the openSUSE repo file to /etc/zypp/repos.d/." How is this done and where? This needs more instruction please.
