Systemd boot hangs after disabling NetworkManager

Question

I disable Network Manager via

systemctl disable NetworkManager

and reboot. The boot process hangs. Via whatever means, I access the filesystem, create symlinks with

ln -s /etc/systemd/system/multi-user.target.wants/NetworkManager.service \
/lib/systemd/system/NetworkManager.service

And similarly for dbus-org.freedesktop.nm-dispatcher.service. The boot process still hangs indefinitely after attempting to start the NTP daemon (NetworkManager is seemingly started without errors by that point).

Is there anything else I may need to do? Something other than symlink deletion affected by disabling the service?

Answer 1

use init 1 which is single user without networking

use cmdline passing to kernel from grub i.e.

press e to edit on boot screen

you will see find

ro quiet splash

and change it to

ro quiet splash single

and do

systemctl enable NetworkManager
