How do I fix a "Can't access Dropbox folder" error?
if you put these in /etc/sysctl.conf
:
fs.inotify.max_user_watches = 1048576
fs.inotify.max_user_instances = 256
it will fix the issue. You may have to run sudo sysctl -p
for these settings to take effect.
Alternatively, if you are not interested in making these settings permanent, you may try the following commands...
sudo sysctl fs.inotify.max_user_instances=256
sudo sysctl fs.inotify.max_user_watches=1048576
In this case the settings will be lost after a reboot.
The problem is that the system has run out of inotify instances. You can check your syslog (e.g. by using tail -f /var/log/syslog
) and if you see...
tail: inotify cannot be used, reverting to polling: Too many open file
then you know this is your issue. For me it was nepomuk.
