Problem with first apt-get after setting up USB-Stick for Dockstar

Preliminary note: The problem is solved - but as it could possibly cause unnecessary work for others also, I will report it....

I am on a step-by-step trip to revive my bricked dockstar.
After installing a new u-boot via JTAG-Debugger, I am now on the way to get a working bootable USB stick with an not outdated debian.


Now I was stuck on a working step from https://forum.doozan.com/read.php?2,12096.

Note: If this is your first time installation, then you need rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (this has kernel 4.12.1-kirkwood-tld-1 already installed).

After logging in this rootf the first time, remember to generate new SSH key to make it your own unique rootfs. And also update your rootfs to get the latest Debian package security updates:

rm /etc/ssh/ssh_host*
ssh-keygen -A

apt-get update
apt-get upgrade

apt-get update returns on each contacted update server....

Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)

Google-Search returns something about proxies etc, and I tried some of the recipes recommeded on my google findings...

Nothing helps....

And then, I encountered, that it was a configuration that I made for security reasons for the dockstar with the former (totally outdated) squeeze linux.

As this is outdated, and there are no ways to get even security fixes. I decided to cut the connection to internet for the dockstar.

My Fritzbox" home router offers a feature called "Kindersicherung" that gives you the opportunity to configure the devices of your children for limited internet access (whitelist, black lists, maximum usage times etc...).

I used this feature to block the internet access for dockstar completely.

As I re-used the fixed 192.168.x.x IP-adress and MAC of the old dockstar configuration, the old "Kindersicherung" settings block the access to the debian repository servers ....

2 lost hour of lifetime .....

Perhaps, this sudo apt update always giving Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?) will help?

As I sad in thread-opener: The problem is solved (after some useless hours of searching).
Reason was activated "children-protection" provided by my all-in-one home router "fritzbox", preventing internet-access of dockstar.

I have activated it for the MAC of dockstar some years ago for security reasons, since there were no more updates available, and I want to use the old stretch linux further on, but only for access from inside home.

After deactivating "children-protection" for my dockstar in the "fritzbox" web-config-page repository servers were reachable ...
