Call me old school but this is one of my biggest gripes with #ubuntu and the #Linux desktop shift over the past two decades:
Disabling root and using sudo for everything. When *properly* configured, sudo is an excellent security policy tool!
BUT...allowing any user to easily gain admin rights with their own password, even temporarily, without properly understanding the system? That is just asking for disaster through poor practice. This is no different than the convenience of #Windows and #MacOS.
Ubuntu's default sudo configuration means the user only needs their password to brick their system.
sudo chown -R 400 /usr/*
Sorry, I'll get off my soapbox now.
