I think the issue is ipv4 configuration

Have you disabled ipv6?

nope nope

You might try that.

In the meantime, the package is in the Focal Repo:

Please were I disable ipv6

You can set it with a grub parameter

ipv6.disable=1 module_blacklist=ip6_tables

sudo nano /etc/default/grub

add ipv6.disable=1 module_blacklist=ip6_tables right after the splash in "quiet splash" so that it looks exactly like "quiet splash ipv6.disable=1 module_blacklist=ip6_tables"
Tap ctrl+o, then enter then ctrl+x
Now you must run

sudo update-grub

I am not convinced that this will solve your issue... this can be undone by reversing the above back to just "quiet splash" and running sudo update-grub again.

I do not use linux, this is to much terminal for me :slight_smile:
when I look the ip numbers in ipv4 there is nothing
and in cable 2 with iPhone they are present or visible

can I send you 2 pictures?

Yes, you can use the Image Button on the post toolbar to attach images.

Everyone starts somewhere.:wink:

While connected on your iPhone, run in terminal:

sudo apt update && sudo apt full-upgrade

reading packets

erased various packets ,
xgd-desktop-portal not erased

Yes, that can be ignored. There is another thread open about that.

cabled net 2 does not open at usb connection
