I've given up with my solution in #9 as it did not work. I'm still using 14.04 LTS systems and now employ the following fix instead:
service isc-dhcp-server stop setfacl -dm u:dhcpd:rwx /var/lib/dhcp setfacl -m u:dhcpd:rwx /var/lib/dhcp service isc-dhcp-server start Note: For this to work you must have acl support on the root filesystem (assuming that's where /var/lib/dhcp lives on your configuration). This is a matter of adding the "acl" option to the mount line in /etc/fstab. I have been running this for a couple of months now and it seems to do the trick on several servers. Hope it helps someone? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1186662 Title: isc-dhcp-server fails to renew lease file Status in isc-dhcp package in Ubuntu: Triaged Status in isc-dhcp source package in Trusty: Confirmed Bug description: After raring upgrade, the dhcp server fails to renew lease file when it tries to (about every hour). The syslog says: dhcpd: Can't create new lease file: Permission denied It looks like a permission problem, because # chown -R dhcpd:dhcpd /var/lib/dhcp the above command temporarily solves the issue, until dhcpd is restarted: at that time, the ownership of the directory and the lease file is set back to root:root.
