DNS Problems with Mobile Data

[anonymous]

Hello there,

is anyone else facing DNS problems using mobile data after the latest Network Manager update to v1.35.91-1?

I can ping 8.8.4.4 for example but opening a homepage in a browser is not working.

No problems with Wifi though...

Thanks in advance!

Yes I have the same problem since about 24 hours. Thank you for mentioning it here. My Pinephone is my daily driver, I really need to make it work anew.

I reported this bug here:
https://gitlab.freedesktop.org/NetworkMa...issues/931
Please mention your workarounds.

Thanks for the bug report. I think, the problem is that the latest Bookworm version of Network Manager is not forwarding the DNS server adress from mobile networks to the system as it does with the Wifi DNS.

And since I don't like downgrading, here is my workaround as mentioned above from Zebulon Walton:

Code:

sudo apt install resolvconf
sudo nano /etc/resolvconf/resolv.conf.d/head
# add "nameserver IP-ADRESS" --> 9.9.9.9 for quad9 for example
sudo systemctl restart resolvconf.service
sudo systemctl restart systemd-resolved.service

That did the trick for me without downgrading.

Cheers

Yes I saw the same trick here:
https://debian-facile.org/doc:systeme:resolv.conf

"Il suffit de mettre les paramètres que l'on veut dans le fichier « head » présent ici : /etc/resolvconf/resolv.conf.d/

Dès lors, ce sont ces paramètres qui seront repris comme prioritaires dans le resolv.conf" which means

"Just put the parameters you want into the "head" file here: /etc/resolvconf/resolv.conf.d/

From then on, these parameters will be taken up as priorities in the resolv.conf"


I'm going to use these DNS:

P.S: It works as expected, many thanks
