Real Linux fuck up coming up.

Be me.
Working on a project.

Accidentally used sudo with git pull, every file now is only accessible for root users.

Thinking to myself.. okay I'll just do chmod 777 to the current directory

Forgot how to use chmod
At first something like
Sudo chmod ./ 777

Not working
Maybe
Sudo chmod / 777

Not working
Remembering that it's the other way around

sudo chmod 777 /

Now... I fucked up. I forgot the dot, and for a sec I forgot that '/' means root directory and not current like './' does.

Few moments later the permission system of Ubuntu is utterly fucked. Everything is not working.

Need sudo in order to fix everything but sudo isn't working.

Few hours of crying later,I solved it thanks to some nice ppl online helping stupid people like me who used that command...😂
