Please clarify the section where I typed 'cd arduino-1.8.18 [return] sudo ./arduino'. I got its answer as 'exit status 1 [return] too many decimal points in number'. What went wrong? Which screen? Which program? I am pulling my hair out in frustration!

So this happens when you try to start the Arduino IDE? Seems like something is wrong with Arduino IDE installation.
Maybe try re-installing Arduino IDE, maybe try a simpler path without decimal symbols in name. Maybe the Arduino community would know more.
SOLVED!
I found an avoidance to the "no such dir" and "exit status 1 [return] too many decimal points in number" issues. It was on a YouTube channel. It was less painful and faster!
