Can't change the root password

[light wharf]

even if it gets updated, it doesn't work!

make sure you do "passwd root"

also, if its public cloud machine, ensure that your /etc/ssh/sshd_config or whatever file it was named does not have line which blocks password login or requires keyfile to be used even if you permit root login in another line.

I think it was something like "passwordlogin no"

you change it to yes

then save

and then restart ssh/sshd service, or the entire machine with sudo reboot
