Решите проблемы с предупреждением при запуске emacs в Ubuntu

Мой Emacs в Ubuntu всегда показывает предупреждения ниже, что довольно раздражает.

Warning (initialization): An error occurred while loading ‘/home/AROT/.emacs.d/init.el’:  error: Key sequence RET o starts with non-prefix key RET  To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the ‘--debug-init’ option to view a complete error backtrace. 

Затем я последовал инструкции и запустил emacs с командой emacs --debug-initи увидел следующую информацию:

Debugger entered--Lisp error: (file-missing "Cannot open load file" "No such file or directory" "tex-site") require(tex-site) eval-buffer(#<buffer *load*-267398> nil "/home/AROT/.emacs.d/elpa/auctex-11.88.6/auctex-autoloads.el" nil t) ; Reading at buffer position 10037 load-with-code-conversion("/home/AROT/.emacs.d/elpa/auctex-11.88.6/auctex-autoloads.el" "/home/AROT/.emacs.d/elpa/auctex-11.88.6/auctex-autoloads.el" nil t) load("/home/AROT/.emacs.d/elpa/auctex-11.88.6/auctex-autoloads" nil t) package--activate-autoloads-and-load-path(#s(package-desc :name auctex :version (11 88 6) :summary "Integrated environment for *TeX*" :reqs nil :kind nil :archive nil :dir "/home/AROT/.emacs.d/elpa/auctex-11.88.6" :extras ((:url .

Поскольку у меня мало знаний о LISP, кто-нибудь может мне помочь в этом вопросе? Спасибо!
