My YunoHost server

Hardware: Internet Cube without VPN
YunoHost version: 11.2.4
I have access to my server : Through SSH

Description of my issue

Hello,

I’m installing a new yunohost instance on my ARM board (Olimex Lime 2).
Since you don’t maintain official images for ARM boards anymore (according to this post : Installation neuve sur la brique internet non fonctionnelle - #23 by jef), I’ve installed an “Bullseye” armbian image for my board (links).

I flashed the SD card via Balena, installed Armbian, then I followed I used:
curl https://install.yunohost.org | bash
as root on armbian.

Yunohost then get installed smoothly and I can access the webadmin for the post-install. Great!

But then I tried to reboot it, after finishing the post install, and the I can no longer access the webadmin. I can connect via SSH, but nothing else.

I think the nginx config is broken, but I’m a little out of my depth here and don’t know what to do next. Seems something similar to : Interface Web inaccessible - #6 by Aleks but i’m not sure it was resolved.

Here is what nginx -t gives:

nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory)

I didn’t touch anything regarding nginx, but i guess the armbian installation can be responsible ?

Thank you for your help!

Hi,
could you post the result of ls -ali /var/log/nginx?

3

I get:

ls: cannot access '/var/log/nginx': No such file or directory
4

Can you post result of ls -ali /var/log & cat /etc/fstab?

Here it is:

Does :

mkdir /var/log/nginx
touch /var/log/nginx/error.log

Fix it?

7 
mkdir /var/log/nginx
touch /var/log/nginx/error.log

did it!

I could then yunohost service start nginx
and the webadmin was once again available! Thank you!

The diagnosis shows on the other hand other problems: fail2ban, redis-server and rspamd can not be started. Here’s the log for redis:
