Saya telah mengatur apt-mirror
dan mengunduh paket ubuntu terbaru dengan sukses di mesin yang dapat mengakses internet. Tujuannya adalah untuk menggunakan mesin ini sebagai repositori ketika melakukan apt-get update
pada mesin target yang tidak dapat mengakses internet. Kedua mesin telah diatur dengan alamat IP manual, dan kedua mesin berjalan dengan Ubuntu 16.04 sebagai OS. The etc/apt/sources.list
di mesin target hanya memiliki 1 baris:
deb http://<local_repo_IP>/ubuntu/ xenial main restricted multiverse universe
Tetapi ketika saya melakukannya sudo apt-get update
pada mesin target, saya mendapatkan kesalahan berikut:

Pada mesin target:
The
/etc/resolve.conf
file berisi berikut:# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.1.1
Ini
/etc/network/interfaces
berisi yang berikut:# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback
Juga, karena satu-satunya baris dalam output apt-get update
yang secara eksplisit mengatakan kesalahan adalah Err:3 http://<local_repo_IP>/ubuntu/dists/xenial main/restricted amd64 Packages
, saya memeriksa apakah file ada dengan melakukan hal berikut di mesin target
wget http://<local_repo_IP>/ubuntu/dists/xenial/restricted/binary-amd64/Packages
Dan saya melihat bahwa file itu ada di sana, karena saya mendapatkan output berikut:

Saya juga memeriksa untuk melihat apakah saya dapat melakukan ping dengan sukses dari mesin target ke mesin repo. Itu juga berhasil.

Jadi, apa yang salah dengan itu apt-get update
? Bagaimana saya bisa memperbaikinya dan membuatnya berfungsi?
PS Saya hanya memperhatikan bahwa kesalahan mengatakan http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages
. Mengapa mencoba mencari restricted
paket di dalam main? Bukankah seharusnya melihat ke dalam http://<local_repo_IP>/ubuntu/dists/xenial/restricted/binary-amd64/Packages
? Memang ketika saya melakukannya wget http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages
, itu memberikan kesalahan berikut:
--2017-12-21 17:26:06-- http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages

HTTP request sent, awaiting response... 404 Not Found
2017-12-21 17:26:06 ERROR 404: Not Found.
Apa yang terjadi di sini? Mengapa ia mencoba memeriksa direktori yang tidak ada? Dan bagaimana cara apt-get update
menunjukkan jalur yang benar?
