NetworkManager NMClient object lost

sudo nmcli d
NetworkManager is not started
sudo NetworkManager && sudo nmcli d
nmcli: NMClient object not found: no such file or dir
But before bootup I seperated /usr/share into /dev/sda20 (my final fs is /dev/sda24, total 24 partitions, 12 are Linux root fs) also finished migrating from root to /dev/sda20 with any stuff missing, before seperation my /usr/share is on root fs /dev/sda2.
