[Bug 1448657] Re: isc-dhcp-server: Can't create PID file /run/dhcp-server/dhcpd.pid: Permission denied
So I found a comment at https://unix.stackexchange.com/a/533900/253840 > My problem was that I had two services using same RuntimeDirectory (isc-dhcp-server and isc-dhcp-server6), but I configured only one to work. So when the second one died, its runtime directory got removed, making it a problem for the first service. Since I have only the IPv4 addresses configured as well, I decided to look into this. When I tested this out by changing the RuntimeDirectory to "dhcp- server6" and the exec line's PID file parameter to "-pf /run/dhcp- server6/dhcpd6.pid", everything worked as it should on a reboot. The PID file was created for /run/dhcp-server/dhcpd.pid successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448657 Title: isc-dhcp-server: Can't create PID file /run/dhcp-server/dhcpd.pid: Permission denied To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1448657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1448657] Re: isc-dhcp-server: Can't create PID file /run/dhcp-server/dhcpd.pid: Permission denied
I'm encountering the same thing on a fresh installation of Ubuntu 20.04.
