Thanks. Do you know the answer to my question here askubuntu.com/questions/610537/…? I don't know which one of the two replies should I follow.

comment Error adding a repository to /etc/apt/sources.list
he also said "As you are using Ubuntu 14.04 und already have trusty-backports activated there isn't any reason to use the package source anyway. Just remove it." If you think that I should add something, suppose I pick http://stat.ethz.ch/CRAN/, what line do you suggest to my /etc/apt/sources.list then? Note that I have already added deb http://stat.ethz.ch/CRAN/bin/linux/ubuntu trusty/.

comment Error adding a repository to /etc/apt/sources.list
Thanks. (1) Suppose I pick http://stat.ethz.ch/CRAN/, what line do you suggest to my /etc/apt/sources.list then? (2) Is my question about R cran mirror or about ubuntu mirror? I though it was the latter? But your reply imples the former?

Thanks! What harm can it make without running the commands in your reply? Will I still update and upgrade correctly?

comment Possible to let virtualbox guest OS to use some device directly?
@ΝίκοςΦυτίλης: "try using an external usb wifi card (should work)", do you mean that the guest Windows can use an external usb wifi card directly, even though the host Ubuntu can't use it either?
