[SOLVED] What does "pacman -Syuu" and "pacman -Syy" do?
I have read in the MATE install page there are these two commands:
pacman -Syuu
pacman -Syy
But what do these mean? Filter old version packages two times or something?

man pacman will tell you what those do. The wiki says exactly why that needs to be done. It doesn't suggest running BOTH of those in sequence though - they are under different headings for different purposes.

Opps! I had read it but didn't check the last sentence of the -y option 
Thanks!

Re: [SOLVED] What does "pacman -Syuu" and "pacman -Syy" do?
I wanted to find this answer here, so I'm putting it here:
pacman -Syuu:
-S: Sync packages
-y: refresh package database
-uu: sys upgrade all packages, repeated 'u' flag enables downgrades (from man page):
Pass this option twice to enable package downgrades; in this case, pacman
will select sync packages whose versions do not match with the local
versions. This can be useful when the user switches from a testing repository
to a stable one.
pacman -Syy:
-S: Sync packages
-yy: refresh package database, force refresh even if local database appears up-to-date
