نمیدونم فیل تر نیست؟

تمام کاری که باید می کردی این بود که اون لینک رو با مرورگرت باز کنی و ببینی داستانش چیه! =>( بخوان در نتیجه ) اگر این کار رو میکردی ۱ روز جلو میافتادی، نه؟
حالا اگر سوالت رو به انگلیسی جست و جو می کردی، اولین نتیجه به این (http://debgen.simplylinux.ch/) میرسیدی، یا اگرم انگلیسیت خوب نیست فارسی تو همین انجمن جست و جو می کردی به این (http://forum.ubuntu.ir/index.php/topic,98857.msg809342.html#msg809342)( که مشکلتو یه بار حل کرده! ) میرسیدی => ۴روز که معادل ۹۶ ساعت باشه جلو میافتادی!

اینجاست که میبینیم چرا حرفه ای ها کمتر سوال می کنن.

پس محتویات پرونده ی etc/apt/sources.list/ رو به:

کد: [انتخاب]

deb http://ftp.debian.org/debian unstable main contrib non-free

deb http://ftp.debian.org/debian/ Sid-updates main contrib non-free

deb http://security.debian.org/ Sid/updates main contrib non-free
تغییر بده.

مشکلی که بیان کرده اینه:

کد: [انتخاب]

Could not resolve 'ftp.debian.org

یعنی با DNS مشکل داری. با کاربر ریشه این دستور رو بنویس و ببین مشکل حل می‌شه یا نه:

کد: [انتخاب]

echo -e "nameserver 8.8.8.8\nnameserver 4.2.2.4" > /etc/resolv.conf

در ضمن، مخازنی که داری برای SID هستش، یعنی از Debian 7.6 استفاده نمی‌کنی!

نشد که جواب نیست :) اینطوری عموما جوابی مثل این می‌گیرید: پس نمی‌شه!
خروجی دستوراتی که زدید چیه؟

بالاتر هم جواب سوال اول رو دادم، شما مخازن Debian SID یا همون Debian Unstable رو دارید.

خوب یحتمل اگر DNS مشکل داشته باشه نباید بتونه خیلی از سایت ها رو باز کنه. اگر مثلا این جا رو میتونه نیم رزولیشن کنه دلیل نمیشه که اون جا رو هم نیم رزولیشن کنه؟ مگه ساختار DNS سلسله مراتبی نیست؟ یکم توضیح میدید؟

به دلیل نوع ساختار DNS (پروتکل UDP، مقادیر Cache شده، ...) به راحتی نمی‌شه مشکلات DNS رو پیدا کرد و نیاز به تست‌های مختلفی داره، ولی وقتی چیزی Resolve نمی‌شه، اکثر مواقع مشکل از DNS هستش.
