I can’t get firewall to work in Peppermint 4. It says the device USB0 is not ready. I am connected to my mobile WiFi.
Which firewall ?
Have you tried starting the firewall before connecting the USB ?
The firewall pre installed with PP4. There isn’t a usb attached. The WiFi is from my phone (unattached)
Bump! 
So what happens if you enable the gufw firewall without the USB connection … then establish the connection ?
Mark, there is no usb connection.
Mark, there is no usb connection.
That could be an internal USB connection, like webcam etc…

OK, that’s blown that idea out of the water … I was expecting a USB wireless adapter ???
I take it you’ve tried removing ALL USB devices ?
can you run:
dmesg > ~/dmesg.txt
you’ll now find a file called dmesg.txt in your home folder … add it as an attachment to your next posting.
OK. I think I should give a bit more info’.
I can get it to work if I enable it but as soon as I exit the program it shuts down. So every time I want a Firewall I have to re start it.
Sorry. Just worked out how to send it by attachment. :-[
Erm … are you misunderstanding the gufw interface ?
When you first start the GUI from menu>System Tools>Firewall Configuration it will APPEAR to be switch OFF until you hit the “Unlock” button … but if when you hit the “Unlock” button it’s then enabled without you having to hit the “ON/OFF” button … then it IS running at bootup.
Open a terminal, and run:
sudo ufw enable
Now REBOOT.
Once rebooted, send the output from:
sudo ufw status
Status active.
Thanks
Yup … it’s working
