Public bug reported: Hello,
If the umask is set to 077 in /etc/profile and /etc/bash.bashrc (to comply with CIS-CAT recommendations), the files that netplan generates in /run/systemd/network are created as 0600 and systemd-networkd will not start. $ ls -l /run/systemd/network total 4 -rw------- 1 root root 152 May 2 14:14 10-netplan-eth0.network $ sudo systemctl start systemd-networkd Job for systemd-networkd.service failed because the control process exited with error code.
