Operating system software
At last, we are copying files and actually installing the operating system.
When the installer gets to the kernel and kernel related files, that part will take a little longer.
The installer might seem like it’s stuck, but don’t panic, it’s not.
After the core OS files are copied, the installer needs to update Apt.
If you use an HTTP proxy to access the Internet, configure it here.
Apt will make use of Internet resources to continue the installer.
There is some other, certainly important, pop up along the way.
