I tried to install a fresh copy of Nextcloud (via NCPi) ona freshly installed Debian Linux. And to my surprise the installation failed with an error related to systemd-resolved.
I see that the issue is discussed here.
But the instructions for solving it aren’t really clear (at least not to me).
So I created a list of step-by-step instructions on how to fix/bypass it.
1. Install systemd-resolved
First, install the systemd-resolved package, which is required to handle DNS resolution in many cases:
sudo apt-get install systemd-resolved
2. Enable and start systemd-resolved
Once installed, enable and start the systemd-resolved service to ensure it is running properly:
sudo systemctl enable systemd-resolved
sudo systemctl start systemd-resolved
3. Check the status of resolvconf
If resolvconf is installed, check its status to ensure there are no conflicts:
sudo systemctl status resolvconf
If the service is inactive or disabled, that’s fine since systemd-resolved will handle DNS resolution.
4. Backup and create a new resolv.conf
Sometimes, the /etc/resolv.conf file can be incorrectly configured or missing. Back up the current file and create a new one using Google’s public DNS (or another DNS of your choice).
Backup the existing file:
sudo mv /etc/resolv.conf /etc/resolv.conf.bak
Create a new resolv.conf file with Google’s DNS:
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf
Alternatively, you can use Cloudflare’s DNS:
echo "nameserver 1.1.1.1" | sudo tee /etc/resolv.conf
5. Restart the network service
Apply the changes by restarting the network service:
sudo systemctl restart networking
6. Test DNS resolution
After restarting the network, test DNS resolution to ensure it works properly by pinging a well-known website:
ping google.com
If the ping works, DNS is now functioning correctly.
7. Re-run the NextCloudPi installation script
Once DNS resolution is fixed, you can re-run the NextCloudPi installation script:
curl -sSL https://raw.githubusercontent.com/nextcloud/nextcloudpi/master/install.sh | sudo bash
Hope this helps anyone facing similar issues!
