I have currently no idea what's going wrong. This happend on two servers running Trusty. -- 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: Fix Released Status in isc-dhcp source package in Trusty: Triaged 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.
