Answer 1

不需要新的存储库——只需安装emacs24你想要的包。

来自我的 12.10 系统：

edd@max:~$ COLUMNS=80 dpkg -l | grep "^ii  emacs"                           
ii  emacs-goodies- 35.2ubuntu2  all          Miscellaneous add-ons for Emacs

ii  emacs23-common 23.4+1-4ubun all          The GNU Emacs editor's shared, ar

ii  emacs24-common 24.1+1-1     all          GNU Emacs common non-DFSG items, 
ii  emacsen-common 2.0.3        all          Common facilities for all emacsen
edd@max:~$

所以只需sudo apt-get install emacs24加上你喜欢的任何附加包。这允许 emacs23 和 emacs24 共存，emacs23 提供默认值。（您可以覆盖它，请参阅man dpkg-alternatives）。
