Please ensure that you are running the latest version of the beta code. Run pihole -up to update to the latest, then verify that the problem still exists before reporting it.
Problem with Beta 5.0: [Hello, I'm receiving a ftl error, and it's not able to connect to obtain the latest release.]
No, not on the pihole. It returns a "Temporary failure in name resolution".
That is with "ping github.com", "ping www.github.com", or I even tried ping -c 3 -i 5 www.github.com". Actually even attempting to ping google. Maybe I need to reinstall the OS? And then the pihole? Start from scratch?
Chances are your device is configured to only use itself for DNS lookups, which is quite common with pihole setups, and now pihole isn't running then resolution is failing.
If you can ping 8.8.8.8 as Dan suggests then just add another nameserver line to /etc/resolv.conf (note - this temp change should get you back up and running for you to get pihole installed)
sudo nano /etc/resolv.conf nameserver 8.8.8.8
once you add this line and save the file, DNS resolution should work again when it realises your localhost name server is down.
Edit: ah, posted too soon. If you want to install the beta from scratch you can use the steps here Installation beta - #3 by DL6ER
Ok, after being under the weather, I was able to do the complete reinstall. This worked fine! And I'm loving the new features. Still not ready to switch the ship back fully over to the pi ad of yet. But just trying out the new feature of power client at the moment..
