Cannot backup (and thus update) Netdata

What type of hardware are you using: VPS bought online
What YunoHost version are you running: 12.0.17
What app is this about: Netdata

Describe your issue

I try to update Netdata and it fails, either in the webadmin or in CLI.

The file “netdata.conf” is missing (as you can see in the log pasted below). I could copy an existing file and adapt its content, maybe it could suffice. I’m afraid to uninstall and reinstall because I don’t know if my settings will be kept.

What can I do? Thanks in advance!
