sshd not working after system upgrade odroid hc2

Recommended Posts

So my sshd service won't start after a system upgrade. I have no uart access, so currently no console access. I do have access to the root drive on a usb device.

I suspect systemd is having a problem starting sshd from the ssh.service unit file. But I'm not sure how to fix it. Any suggestions would be much appreciated.

 

Here are the contents of my ssh.service file. I checked that /etc/ssh/sshd_not_to_be_run doesn't exist. I'm a little confused about the runtime directory, so I made a folder in the root directory called sshd with 0755 permissions, but that doesn't seem right.

 

Strangely I couldn't find anything in the syslog file that mentioned ssh.

Also, here are the contents of /etc/armbian-release

Next kernel v5.97 is not very stable.

 

I didn't realise I was on an unstable kernel. That makes sense now though. I'll keep poking around and see what I find.

 

Thanks for the comment.

I'm pretty sure I found the problem. It's a bad file-system.

 

I think the cause of the bad filesystem was usb 2.0 hub with a long cable. I had the root drive (thumb drive) plugged in at the end of this long cable.

 

I noticed in the documentation it mentions most problems are caused by either a bad file system or a bad power supply.
