I was trying for hours to install mysql-workbench and yaourt didn't find the package.
I found the solution on a Manjaro forum.
replace AURURL='http://aur.archlinux.org' with AURURL='https://aur.archlinux.org'
it's Just a 'S' missing but... it's a bug.
Can you tell me where to report it?
Before you report a BUG, you should update to the current version
Thanks googol-1, This was my first time with yaourt -Sau ... :$
