HI ALL!

  • I HOPE I DIDN’T BREAK EVERY APP/ETC IN YUNOHOST AND THIS IS REPAIRABLE
    PREFACE: I’M SO/SO AND WOULD SAY A LITTLE TECHY BUT AM NO DEV

:uk:/:us: Message template (english)

I have been trying to figure out a wordpress issue (any tips? trying to setup a theme, it says WP uploads directory needs to be writable… I thought it was, I made it and still an error, anyway not for this post) and in doing so I think I deleted something I shouldn’t.
Now when I reboot or try to start fail2ban I get the error

Now I guess I understand what this says. There’s 2 problems. I have no idea how to fix either of them and ensure it still works with my stuff. I cannot get emails or anything right now, please help I have spent two days trying to troubleshoot this but believe I am indeed too stupid. Thank you in advance.

My YunoHost server

Hardware: Old computer at home - AMD 5700G
YunoHost version: 11.1.18
I have access to my server : Through SSH | direct access via keyboard / screen

Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes - I think I 100% deleted something when trying to undo something else that didn’t work to fix a wordpress issue which are likely the two things causing the fail.

y’all!

I did this:
specify the backend in /etc/fail2ban/jail.conf to use systemd by editing the following line:

backend = auto
```TO
backend = systemd



Then restart fail2ban by running (or use yunohost admin panel):
systemctl restart fail2ban



I THIIIIINK it's working
