The link is working whenever I try to download it outside of Linux / VirtualBox, but not inside.
Also ping some random website doesn't work but I have read that's a commmon issue at VirtualBox.
It even can't ping my own router, I have just noticed and giving me this error:
'connect: Network is unreachable'
At the moment I have put the network options to NAT.
EDIT: I found the solution to this problem which is by simply re´nstalling. Installed some packages and turning the internet connection switch on before the installation.
