@aapanel_sniper , @aaPanel_Jose any update for Fail2Ban can't Start for Linux 8 oracle free Tier ? here the error log 2021-12-23 08:53:05 (96.6 MB/s) - ‘/lib/systemd/system/fail2ban.service’ saved [693/693] sed: can't read /etc/fail2ban/jail.local: No such file or directory sed: can't read /etc/fail2ban/jail.local: No such file or directory *.info;mail.none;authpriv.none;cron.none /var/log/messages Synchronizing state of fail2ban.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.

i found the error and bug where the Fail2ban Manager in plugin aapanel are used old version where the beta / dev version i got at the logfile = file2ban -- and the solution i make update via install fail2ban via terminal and the final result where i can use fail2ban with latest version like the screenshot below : -- But at the panel Fail2ban i was install have conflict/bug where the panel say please start fail2ban and at the terminal are active here : at terminal fail2ban status are running active using latest version So my conclusion where the panel plugin have used old update fail2ban v1.8 manager - where i am using Nginx 1.21.4 and System: Red Hat Enterprise 8.5 (Ootpa)(Py3.7.8) Hope the Dev/Support can fix this cc @aapanel_sniper , @aaPanel_Jose That all Thanks.

@DevTeam please fix this issue asap.

I also got the same Fail2ban error on new install on Almalinux, l had to install the fail2ban manually otherwise it won't start correctly. However fail2ban module on front end can't handle this fail2ban version. please fix it. To install fail2ban correctly in the mid time do: sudo dnf install fail2ban fail2ban-firewalld systemctl start fail2ban systemctl enable fail2ban systemctl status fail2ban you can check is running, if you try to add the rules manually in fail2ban frontend module settings it will tell you the rules already exist.

creative Almalinux? no offense but you cant ask for a fix for a non-supported distro

wget -O /tmp/fail2ban.tar.gz http://download.bt.cn/install/plugin/fail2ban/fail2ban.tar.gz -T 5 cd /tmp tar -zxf fail2ban.tar.gz cp /tmp/fail2ban/files/debian-initd /etc/init.d/fail2ban cd /tmp/fail2ban btpython setup.py install This is the process of installing fail2ban manually, during the installation, if you encounter any errors, please take a screenshot

How to Fix Fail2Ban on Oracle Linux 8?

Uninstall Fail2ban Manager on Oracle Linux 8.

Now go to terminal Run this command:

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -y

After the above command run another command on terminal

sudo dnf install -y fail2ban

Now after that, go to AAPanel's App Store and install Fail2Ban Manager 1.9. This time Fail2Ban Manager 1.9 will work great!
