Old Thread, but I was stuck with a similar Issue related to Temporary failure resolving 'security.ubuntu.com' Turns out in my Case I had to specify a custom NAMESERVER Build Switch. Looking at the Reference Guide, the NAMESERVER Environment Variable defaults to 1.0.0.1. https://docs.armbian.com/Developer-Guide_Build-Switches/#hidden-options-for-advanced-users-default-values-are-marked-bold In my Case however, a DNS Block is enforced on my Main Router for all direct DNS Requests to any Nameserver (except the approved local DNS Servers, which are the only ones that can forward DNS Requests to Upstream DNS Servers). The Solution was quite easy once that was figured out. Just pass a local DNS Server as part as the Build Command 😃: compile.sh \ build \ NAMESERVER=192.168.1.3 \ ... I only came across the Reference Guide by Chance. It was tricky because the Docker Container used for the build Process could resolve any host successfully (e.g. curl -4 ifconfig.me or even curl -6 ifconfig.me), but I guess that either another Container (Docker inside Docker) or systemd-nspawn does something weird of its own.

Still good to know that at least it's supported, even though it needs a custom (non-mainline) Kernel for now . I'm a bit surprised they are still using 6.1 Branch, but fair enough, that is Longterm Support (as would be 6.6 and 6.12), but kinda weird they are using such an old Version. The exact Version they seem to be using is 6.1.115, released 2024-11-01 (01-Nov-2024), as opposed to latest 6.1.140 released on 2025-05-22 (22-May-2025). However the Build Log that Igor pointed me to was 6.1.99-vendor-rk35xx, so yet another Version. But maybe that isn't the latest Build or ? Installed Packages in that Log point to 6.1.115 ii linux-dtb-vendor-rk35xx 25.8.0-trunk.53 arm64 Armbian Linux vendor DTBs in /boot/dtb-6.1.115-vendor-rk35xx ii linux-headers-vendor-rk35xx 25.8.0-trunk.53 arm64 Armbian Linux vendor headers 6.1.115-vendor-rk35xx ii linux-image-vendor-rk35xx 25.8.0-trunk.53 arm64 Armbian Linux vendor kernel image 6.1.115-vendor-rk35xx

Actually I just discovered this PR right now: https://github.com/armbian/build/pull/7820 Interesting, so basically Armbian will use the old Kernel that Radxa Originally shipped with their Images (I don't think they ever shipped anything newer than Bullseye which is very old now). So essentially we can run the recent Ubuntu Noble / Debian Bookworm Distributions, "just" with the old Kernel from Debian Bullseye ?

I would really like to get the Radxa Rock 2F (with Rockchip RK3528A) board as a KVM Adapter because it's very cheap (~ 12 USD / EUR including Taxes). I read that at least the RK3528 SOC is just getting Mainline Support for the Clock as in Kernel 6.15. No USB, Ethernet, PCIe or GPU support at all right now. I don't know how similar the RK3528 and RK3528A are, I couldn't find much Information on the Internet. At the very lead I would need MicroSD, Ethernet and USB (including USB OTG) working. I saw there is a Repository with some Notes for the RK3528 SOC on Github, outlining the Status of getting Mainline Support: https://github.com/ziyao233/rk3528-mainline @Igor mentioned a few Months ago on Github that he planned on getting the Radxa Rock 2F Board soon, but no Timeline available yet: https://github.com/armbian/build/issues/7836#issuecomment-2662772344 @Igor: did you have a Chance to play a bit around on the Radxa Rock 2F ? Is anything working right now ? Thanks for the Help !
