Persistent DNS resolution issues in Ubuntu 22.04 after changing network settings
I'm wondering if anyone has experience with I'm relatively new to this, so bear with me. I'm dealing with I'm a bit lost with I tried several approaches but none seem to work... I'm experiencing persistent DNS resolution issues on my Ubuntu 22.04 system after modifying my network settings to use a static IP. I set the static IP configuration in the `/etc/netplan/01-netcfg.yaml` file like this: ```yaml network: version: 2 renderer: networkd ethernets: eth0: dhcp4: no addresses: - 192.168.1.100/24 gateway4: 192.168.1.1 nameservers: addresses: - 8.8.8.8 - 8.8.4.4 ``` After applying the changes using `sudo netplan apply`, the static IP appears to be set correctly, and I can ping the gateway without issues. However, when I attempt to resolve any domain name, I get: ``` sudo: unable to resolve host my-ubuntu: Name or service not known ``` Additionally, commands like `ping google.com` unexpected result with a `ping: google.com: Name or service not known` message. I've checked `/etc/resolv.conf`, and it seems to be pointing to the correct nameservers: ```plaintext # Generated by netplan nameserver 8.8.8.8 nameserver 8.8.4.4 ``` I also verified that the `systemd-resolved` service is running with `systemctl status systemd-resolved`. Restarting the service does not resolve the scenario. I tried flushing the DNS cache with `sudo systemd-resolve --flush-caches`, but it didn't help either. I initially thought there might be a conflict with NetworkManager, so I stopped it with `sudo systemctl stop NetworkManager`, yet the question continues. Does anyone have insights on how I can troubleshoot or resolve this DNS scenario? I'd really appreciate any guidance on this. I'm working on a service that needs to handle this. Any help would be greatly appreciated! I'm on Windows 11 using the latest version of Bash. I'd love to hear your thoughts on this. I'm using Bash 3.11 in this project. What's the correct way to implement this? My development environment is Linux. Thanks, I really appreciate it!
