Hi,
Today I tried to install debian from a CD which dated back to 2011.
Everything went fine,
partition -> and then it arrived at the set up the mirror, I just choose default and think later changed in the /etc/apt.
It started to download from that default ftp mirror.
It was choked there for half a hour, the progress bar didn't proceed and it is said waiting ...
The only thing I could do at that time, was took the CD out and reboot. Which I shouldn't have done that.
