Hi there,
I have recently updated two of my devices and after rebooting, the network connection remains but no website loads. Pinging the website works, so it is DNS. I never touched the network settings besides joining a network through KDE, and certainly never interacted with DNS. Here is my update log that I just did using:
Code:
cat /var/log/apt/history.logCode:

automatic)End-Date: 2026-01-25 17:13:20To anyone who also gets this problem, and to resolve the issue, but first needs to verify if it is actually DNS, I entered the command:
Code:
sudo bash -c 'echo -e "nameserver 1.1.1.1\nnameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null'Low and behold, it is a DNS problem, and now DNS temporarily works and websites resolve. While the internet worked, I installed systemd-resolved as it was recommended:
Code:
sudo apt install systemd-resolvedNext, I need to write parameters to 00-use-resolved.conf:
Code:
sudo tee /etc/NetworkManager/conf.d/00-use-resolved.conf > /dev/null <<'EOF'>[main]>dns=systemd-resolved>EOFNow, you need to enter the command which creates a symbolic link from stub-resolv.conf to resolv.conf, redirecting DNS queries to the systemd-resolved service.
Code:
sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.confNow, go to the directory as follows and place in your DNS settings:
Code:
sudo nano /etc/systemd/resolved.confMine are:
Code:
[Resolve]DNS=116.202.176.26#dot.libredns.grFallbackDNS=127.0.0.1 ::1#Domains=#DNSSEC=noDNSOverTLS=yes#MulticastDNS=yes#LLMNR=yes#Cache=yes#CacheFromLocalhost=no#DNSStubListener=yes#DNSStubListenerExtra=#ReadEtcHosts=yes#ResolveUnicastSingleLabel=no#StaleRetentionSec=0You should now have DNS after restarting systemd-resolved and NetworkManager:
Code:
sudo systemctl restart systemd-resolved NetworkManagerI'm unsure which package caused this, as it has happened to two of my devices after updating. Any ideas?
