repull.sh still needs password

[meyerhaven]

Hey guys,

i have set up the repull script with my remarkable2. This works already. I also have set up ssh-keys like the method in the wiki. If I connect from host to remarkable with "ssh 'root@ip adress'" i don't need the password. But if I start the repull.sh I still need a password. Is there any parameter when executing the repull.ssh wich i have to choose?
I call it like:

sudo bash /usr/local/bin/repull.sh -o /home/pi/folder -r xxx.xxx.xxx.xxx /folder/document
