Hi all,
I’ve read the forum before posting and could’nt find any explanation.
Here is my problem : i cannot access internet through domain names. It worked and after a reboot, it doesn’t.
Here are the things i have checked :
- wifi or ethernet networks are OK, i use them on another computer
-
$ping 8.8.8,8
is OK while$ping example.com
returns “temporary failure in name resolution” (from french to english) - i can surf with a live key OS like Tails
- Networks are recognized on the NetworkManager GUI and tells me i am connected to wifi or ethernet
So i am suspecting a local DNS resolver issue.
Below some system information that may be of some interest :
$sudo systemctl status NetworkManager
