osx - Homebrew won't update, but no error occurs -


i'm using homebrew on os x el capitan. worked long time, doesn't want update nor packages. when run brew update says already up-to-date., though it's not newest version. brew --version is:

homebrew 0.9.9 (git revision 06fe3; last commit 2016-08-10)

homebrew/homebrew-core (git revision a059; last commit 2016-08-10)

this 1 month old, , of packages got updates since then, homebrew doesn't want update them. when run brew doctor, says:

your system ready brew.

why won't homebrew update?
