Hi

I want to install some packages, but it not found on sources. When i do update repositories by sudo apt update command, the following messages shown that means the repositories is broken.

Err:1 http://httpredir.debian.org/debian stretch InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead.

Also i tried sudo apt update --fix-missing and sudo aptitude update or sudo apt-get update but nothing changed.

I'm using Armbian_5.38_Cubietruck_Debian_stretch_next_4.14.14

How can i fix this? Is there a new source list to replace?

Thanks.

Problem is DNS related. If you are getting IP via DHPC server, which is default, this is what you need to do:

rm /etc/network/interfaces
reboot

I'm using static IP, but my internet connection is shared true another Ethernet connection that gets IP from DHCP server.

is it works for my situation?

 

Don't know. This error indicates that something is wrong with your network, most likely DNS settings. Unrelated to Allwinner A20 or Armbian.

Thanks a lot!

@Igor

True, the problem was related to DNS. I've fixed it by adding DNS nameservers as follow:

 

$ sudo vi /etc/resolv.conf

Modify or enter nameserver as follows:
nameserver 8.8.8.8
nameserver 4.2.2.4

 

Thank you once again!
