Odroid Hc1 Docker & Wireguard

[viking3r]

Hello, 

 

I own two odroid hc1 both run on armbian buster Kernel 4.14.222.

With my second one I am experiencing something odd.  I tried setting it up as a webserver with docker multiple times, at some point I have to reboot and then it never comes back up (not reachable via ssh).

Now after each package install I tried rebooting to see if it comes back up. 

Below is a list of things I did in armbian after initial boot.

- apt update --> reboots fine

- apt dist-upgrade --> reboots fine

-change hostname --> reboots fine

- add docker armhf repository 

-install armbian to disk --> reboot stuck but with power cycle booted up

- apt install docker-ce docker-ce-cli containerd.io 

-apt install docker-compose --> reboot fine

-apt install wireguard from buster-backports via clia (-t option) --> no reboot possible, powercycle has no effect, the green led is on but not flashing, blue is flashing. drives makes some noise after powercycle, not reachable via ssh.

 

I am a bit clueless what I am doing wrong. Is it the board, is it linux or is what I am doing the problem?

 

I unfortunately do not own an UART USB-Debugging device. But if anyone can recommend something I will buy it.

Update: 

 

So it turns out the fact I installed wireguard and docker and the hc1 wouldn't reboot after that was more or less random.

I was able to replicate the not booting issue without installing these.

 

I bought an uart adapter to be able to understand more what is going on. 

Here is the output:

Starting Kernel stays there forever no further progress.

 

 

I am not sure about the armbianenv missing and why the boot.ini is missing ?

[tparys]

Sounds like the install to disk probably didn't work smoothly?

 

It may be as simple as copying missing /boot files from your SD card to your disk.

 

Providing armbianmonitor -u on your working HC1 may provide more useful information.

So another try:

 

I did a fresh install on sd card:

moved install to hdd then update (via sudo apt update /upgrade)

 

couple of random reboot attempts --> works

 

installed wireguard:

 

during the install this appears:

 

Setting up linux-image-5.10.0-0.bpo.5-rt-armmp (5.10.24-1~bpo10+1) ...
I: /vmlinuz.old is now a symlink to boot/vmlinuz-4.14.222-odroidxu4
I: /initrd.img.old is now a symlink to boot/initrd.img-4.14.222-odroidxu4
I: /vmlinuz is now a symlink to boot/vmlinuz-5.10.0-0.bpo.5-rt-armmp
I: /initrd.img is now a symlink to boot/initrd.img-5.10.0-0.bpo.5-rt-armmp
/etc/kernel/postinst.d/initramfs-tools:

 

Dunno if this is intended. But I would guess that replacing the kernel image is not a good thing ?

 

I am not a linux pro so maybe its nothing. 

 

After reboot with wireguard the device does not come back up anymore.

 

Will try armbianmonitor -u  as well.

 

Thanks

So the prior replacement of the linux-image seems to be the culprit

 

Makes sense in hindsight

 

I now installed wireguard via 

 

sudo apt install -t buster-backports wireguard wireguard-dkms wireguard-tools linux-headers-legacy-odroidxu4

 

now it works

 

I rebooted a couple of times no issues there. 

 

So in the end it seems like it was the install of wireguard who led to all of this. 

 

The one time I could reproduce the device not rebooting without having it installed must be something like tparsys said. 

 

 

So for now the problem is solved. And some knowledge was gained

 

I should pay more attention when apt wants to install some packages.
