Temporary failure resolving 'raspbian.raspberrypi.org'

Question

iam not able to update any thing on my pie, iam getting the following error Err:1 http://raspbian.raspberrypi.org/raspbian bullseye InRelease Temporary failure resolving 'raspbian.raspberrypi.org'

nameserver in resolv.conf is 8.8.8.8

this is the ping result root@raspberrypi:/etc# ping google.com ping: google.com: Temporary failure in name resolution

i have previously installed piehole in my pie, but after that i have formatted the memory card and installed the fresh os. Please suggest any fix.

Answer 1

I realize this is super old but in case anyone else stumbles here from google, my /etc/resolv.conf file only had 127.0.0.1 as the dns, after adding 1.1.1.1 and 1.0.0.1 I was able to upgrade.

In order to update the file you need to change the dhcpd file:

sudo nano /etc/dhcpcd.conf

add this to the bottom of the file to add the cloudflare dns servers:

static domain_name_servers=1.1.1.1 1.0.0.1

or alternatively the google domain servers

static domain_name_servers=8.8.4.4 8.8.8.8

then just restart the dhcp service and you should be good to proceed with your upgrades:

sudo service dhcpcd restart

If you have 8.8.8.8 already in the config you could try the cloudflare ones, it's possible you just need to restart the service though.
