Have a dropbox installation running on my VPS for a year or two now and its been working just fine. However, it has reached a size where I have started encountering the rollowing error:
Unable to monitor entire Dropbox folder hierarchy. Please run "echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf; sudo sysctl -p" and restart Dropbox to fix the problem.
when I execute this command I get:
error: permission denied on key 'net.bridge.bridge-nf-call-ip6tables'
error: permission denied on key 'net.bridge.bridge-nf-call-iptables'
error: permission denied on key 'net.bridge.bridge-nf-call-arptables'
error: permission denied on key 'fs.inotify.max_user_watches'
tried editing to change the parameter manually:
sudo nano /etc/sysctl.conf
but then when I run "sudo sysctl -p" after the manual change I still get the same permission denied error
