I am following the steps of the radicale documentation and have got to running it as a service. However, when I ran radicale it failed to start. When I tried to run radicale manually, I get a permission denied error

[CRITICAL] An exception occurred during server startup: [Errno 13] Permission denied: ‘/var/lib/radicale/collections’

I have tried manually using mkdir to create /var/lib/radicale/collections and setting the owner using chown -R radicale:radicale to the “radicale” user, and I have also tried using chmod -R 770.

my config (/etc/radicale/config)
