I write the image on my microSD card and boot, and "sudo apt-get update". "Temporary failure resolving - port.ubuntu.com" Can't update. How to solve this issue?
I downloaded the image from this link. https://wiki.ubuntu.com/ARM/RaspberryPi#Ubuntu_arm64.2FAArch64 I wrote the image by Win32DiskImager.
nameserver 8.8.8.8
(Google's DNS server) to a new line on/etc/resolv.conf
have any effect? It could be a DNS issue, but it's difficult to tell at this stage.
