Last week I installed [Armbian][] on an [Odroid N2L][]. The
installation steps, installation results, and fixes for the problems I
encountered are documented below.
### Installation
1. Download and import the [signing key][armbian-key] (fingerprint
`DF00FAF1C577104B50BF1D0093D6889F9F0E78D5`): \
`wget -O- https://apt.armbian.com/armbian.key | gpg -- import -`
2. Download the current "Debian 12 (Bookworm)" image and the [detached
signature][asc] from the "Minimal/IOT images" section of the [Armbian
Odroid N2L page][armbian-n2l].
3. Verify the [signature][asc]: \
`gpg --verify Armbian_community_25.8.0-trunk.8_Odroidn2l_bookworm_current_6.12.28_minimal.img.xz{.asc,}`
4. Uncompress the image: \
`unxz Armbian_community_25.8.0-trunk.8_Odroidn2l_bookworm_current_6.12.28_minimal.img.xz`
5. Flash the uncompressed image to a MicroSD card: \
`sudo dd if=Armbian_community_25.8.0-trunk.8_Odroidn2l_bookworm_current_6.12.28_minimal.img of=/dev/sda bs=1M status=progress`
6. Mount the second partition of the MicroSD card on `/mnt/tmp`: \
`sudo mount /dev/sda2 /mnt/tmp`
7. Use the instructions and template from [Automatic first boot
configuration][armbian-autoconfig] to populate
`/mnt/tmp/root/.not_logged_in_yet`. My populated autoconfig is
[here][populated-autoconfig], but **it did not work as expected**;
see below.
8. Unmount the second partition of the MicroSD card.
9. Insert the MicroSD card into the [Odroid N2L][] and power it on.
### Installation Results
Worked as expected:
- Successfully booted.
- Successfully connected to WiFi on first boot.
Did not work as expected:
- Did not connect to WiFI on subsequent boots.
- Did not set the root password. Instead the root password was `1234`.
- Did not set the user password.
- Did not set the user SSH key.
### Fixes
To correct these problems I connected a keyboard and monitor and did the
following:
1. Logged in as `root` with the password `1234`.
2. Changed the root password and the user password.
4. Edited `/etc/netplan/20-eth-fixed-mac.yaml` and fixed the
errors. The corrected version is below.
5. Ran `netplan apply` to apply the corrected network configuration.
6. Rebooted to confirm that networking was working as expected.
Here is the corrected `/etc/netplan/20-eth-fixed-mac.yaml`:
```yaml
network:
version: 2
```
After fixing networking, I did the following:
1. Copied over my SSH key.
2. Edited `/etc/ssh/sshd_config` to disable root logins and password
logins.
3. Ran `apt-get update && apt-get upgrade`.
4. Installed `unattended-upgrades`.
5. Rebooted to pick up the latest kernel.

TODO: conclusion
The problem with most non-[Pi][] [SBCs][sbc] is the manufacturers
invariably stop providing software updates shortly after the hardware is
released and leave you with unsupported hardware running out-of-date
software.
Case in point: The newest image on the [Odroid N2L wiki][] is Ubuntu
22.04.
original unused blather ...
[Armbian][] now supports the [Odroid N2L][] as a [community maintained
target][armbian-n2l].
Context: A couple of years ago Nadine bought me a pair of [Odroid
N2Ls][odroid n2l]. [Pi 4s][pi] were scarce because of supply chain
issues, and the [Odroid N2L][] seemed like a decent substitute.
The problem with non-[Pi][] [SBCs][sbc] is that the manufacturers
invariably stop providing software updates shortly after release, so you
are stuck with unsupported hardware running an out of date OS.
As of this writing, the [Odroid N2L wiki][] still has the same software
that it did when first got the hardware: Ubuntu 22.04.
