If you have a privately owned Linux PC, you will want to sudo su. It's a hassle to search many times, so I'll leave it here as a memo.
I think that each individual uses a PC differently. The settings below are for my PC, and depending on the individual, you may have to tamper with the settings, so please do so at your own risk.
$sudo visudo
#If you get an error such as not recorded in the sudoers file
$Use su to get root privileges.
I think there is the following description in visudo.
# Allow members of group sudo to execute any command
% sudo ALL=(ALL:ALL) ALL
Rewrite it as follows.
% sudo ALL=NOPASSWD: ALL
Depending on the usage environment, it may be troublesome to start up the PC, so you can log in automatically! I think there are also people. In such a case, turn on the power of the PC and type $ sudo su, and you can do anything, so be careful.
