I own a dell laptop configured with Win-10 Home Edition. For some project, I had to live boot Lubuntu v17.10.1 on it.
The issue is - while trying to get access to 'su account' I am unable to bypass it. It asks for a password, which I have no clue where to find.
I tried using the command - passwd Lubuntu, but it changed password of something else, and not 'su'.
Can someone please guide me how can I obtain password of 'su'? It's important for me to obtain admin rights.
Looking forward to some quick advice and assistance from experts here.
TIA.

In this case, usesudo passwdto set the root password if you really need to, but you should execute most commands that need superuser privilege withsudo.

thanks @WeijunZhou, it worked. :) Also, will this technique of putting 'sudo' work for every command?

Not really by literally putting it before every command. You need to do a little bit work if you have redirections, but generally you can always achieve the goal withsudowithout explicitly invokingsu. If you need something similar tosu, you can just dosudo -i.

Ubuntu assumes that the user should use sudo instead of su by default in their live images as well as their default installation. You can use sudo to do most tasks that can be done by su, but if you really need to change the superuser password, you can do
sudo passwd
This will prompt you for the new superuser password and you can set it. You can then use su as usual.
Alternatively, you can obtain a login shell by sudo -i, or a shell by sudo -s. Both of which give you a shell with superuser privilege. As for the difference between -i and -s, check the manpages.
