Hi,
I have some problem with linux loading and apt command . In installation process by ISO file on Virtualbox , if i tick "yes" for " do you want network mirror ?" part then the Linux doesn't load and just show black screen .

And if i tick "no" for that part , then Linux loads but the 'apt commands' don't work at all . In some cases show this error --> E: can't allocate pkg to ...

But in Virtualbox Image installation version i haven't these problem and it's work well . what is problem .

Sorry for my English.
