Hello! Im new here and encountering an issue with synapse
### My YunoHost server
**Hardware:** VPS bought online (contabo)
**YunoHost version:** 11.2.6
**I have access to my server :** Through SSH
**Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?** : no
### Description of my issue
Fresh install of Debian 11 and yunohost and I can’t install synapse without getting an error from fail2ban.
The green buttons aren’t working for me on my phone so I’m copying/pasting.

Update behaves the same way. BTW that update also crashes Fail2Ban service so better check if it’s running after installation/update.

It’s a core bug, nor a package bug ^^"
I try to patch it here: [fix the fail2ban helper when using using --use\_template arg by OniriCorpe · Pull Request #1743 · YunoHost/yunohost · GitHub](https://github.com/YunoHost/yunohost/pull/1743)
