Tôi đã thiết lập apt-mirror
và tải xuống các gói Ubuntu mới nhất thành công trong một máy có thể truy cập internet. Mục tiêu là sử dụng máy này làm kho lưu trữ khi thực hiện apt-get update
trên máy đích không thể truy cập internet. Cả hai máy đã được thiết lập với địa chỉ IP thủ công và cả hai máy đều chạy với Ubuntu 16.04 dưới dạng HĐH. Trong etc/apt/sources.list
máy đích chỉ có 1 dòng:
deb http://<local_repo_IP>/ubuntu/ xenial main restricted multiverse universe
Nhưng khi tôi thực hiện sudo apt-get update
trên máy đích, tôi gặp lỗi sau:

Trên máy đích:
Các
/etc/resolve.conf
tập tin có chứa như sau:# 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
Có
/etc/network/interfaces
chứa những điều sau đây:# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback
Ngoài ra, do dòng duy nhất trong đầu ra của apt-get update
lỗi đó nói rõ ràng là Err:3 http://<local_repo_IP>/ubuntu/dists/xenial main/restricted amd64 Packages
, tôi đã kiểm tra xem tệp có tồn tại hay không bằng cách thực hiện như sau trong máy đích
wget http://<local_repo_IP>/ubuntu/dists/xenial/restricted/binary-amd64/Packages
Và tôi thấy rằng tập tin ở đó, khi tôi nhận được kết quả sau:

Tôi cũng đã kiểm tra xem liệu tôi có thể ping thành công từ máy đích đến máy repo không. Điều đó cũng làm việc ra.

Vì vậy, những gì là sai với apt-get update
? Làm thế nào tôi có thể sửa chữa nó và làm cho nó hoạt động?
PS tôi chỉ nhận thấy rằng lỗi nói http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages
. Tại sao nó cố gắng tìm kiếm restricted
các gói bên trong chính? Không nên nhìn vào http://<local_repo_IP>/ubuntu/dists/xenial/restricted/binary-amd64/Packages
? Thật vậy, khi tôi làm wget http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages
, nó đưa ra lỗi sau:
--2017-12-21 17:26:06-- http://<local_repo_IP>/ubuntu/dists/xenial/dists/main/restricted/binary-amd64/Packages
Connecting to <local_repo_IP>:80... connected.
HTTP request sent, awaiting response... 404 Not Found
2017-12-21 17:26:06 ERROR 404: Not Found.
Những gì đang xảy ra ở đây? Tại sao nó cố gắng kiểm tra một thư mục không tồn tại? Và làm thế nào để tôi apt-get update
chỉ ra con đường chính xác?
