@anhanyoung91 Hi, I just followed the instructions on the first page.
I did have an issue at one point and it was just because I didn’t follow the instructions exactly as written.
If your getting an error Permission denied: /home/pi to me that sounds like you may not have the path to the vdirsyncer status folder set right. It appears it is trying to write to the /home/pi folder rather than ~/.vdirsyncer/status/
Id go through the steps again and make sure you don’t skip anything.
As for the array issue in the vdirsyncer config I have 2 calendars I sync and the line looks something like this
where home is my main calendar and the random number string is my birthdays calendar.
collections = ["home","57B7E3E-AB79-4DC3-9CF1-A63EB181DB"]
hope that helps
