Hi there! Not long ago, I started using Elementary OS, a Linux distro derived from Ubuntu with the GNOME package manager.
I faced many challenges during the transition from Windows 10 to Linux. Some issues included access permissions, system hang-ups, and minor inconveniences with using the task manager via the terminal.
Okay, without further ado, in this article, I want to share a solution to an internet connection issue in Linux, specifically the error message: "Temporary failure in name resolution."
On the Ubuntu forum, there's a thread discussing this issue. The problem is typically caused by conflicts with NetworkManager, and there are assumptions that it could involve netplan.io, netplan, or even resolv.conf.
Is this happening on a server edition or a desktop edition being used as a server?
If it's a server edition, it seems that systemd-resolved conflicts with netplan. Try this solution:
sudo systemctl disable systemd-resolved
Then reboot your system:
sudo reboot
The result? Amazing! I no longer experience the sudden "No internet access!" issue.
I hope this solution helps you too. Good luck!
