This question came from our site for professional and enthusiast programmers.

No need for new repositories -- just install the emacs24 package(s) you want.

From a 12.10 system of mine:

edd@max:~$ COLUMNS=80 dpkg -l | grep "^ii  emacs"                           
ii  emacs-goodies- 35.2ubuntu2  all          Miscellaneous add-ons for Emacs
ii  emacs23-bin-co 23.4+1-4ubun amd64        The GNU Emacs editor's shared, ar
ii  emacs23-common 23.4+1-4ubun all          The GNU Emacs editor's shared, ar
ii  emacs23-common 23.4+1-1     all          GNU Emacs shared, architecture in
ii  emacs23-lucid  23.4+1-4ubun amd64        The GNU Emacs editor
ii  emacs24        24.1+1-2ubun amd64        GNU Emacs editor (with GTK+ user 
ii  emacs24-bin-co 24.1+1-2ubun amd64        GNU Emacs editor's shared, archit
ii  emacs24-common 24.1+1-2ubun all          GNU Emacs editor's shared, archit
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

So just sudo apt-get install emacs24 plus whichever additonal packages you like. This allows emacs23 and emacs24 to coexist, with emacs23 providing the default. (Which you can override, see man dpkg-alternatives).

so the step is: 1. COLUMNS=80 dpkg -l | grep "^ii emacs" 2. apt-get install emacs24 ? – juanitofatas Apr 29 '13 at 2:07
No, just sudo apt-get install emacs24. What I did was just for display. You can of course also use aptitude, or the Ubuntu Software Center, or whatever other interface to the package system you use. – Dirk Eddelbuettel Apr 29 '13 at 2:10
Ah...Thank you for sharing this! It seems dpkg did not provide the latest emacs. – juanitofatas Apr 29 '13 at 2:13
For this task, you may have confused dpkg with something like apt-cache search emacs. Try that. – Dirk Eddelbuettel Apr 29 '13 at 2:14
@DirkEddelbuettel How is this an answer? The OP clearly asked for Emacs 24.3, which is obviously not present in the standard repositories. – lunaryorn Apr 30 '13 at 7:44

add Damien Cassou’s emacs snapshot PPA

sudo add-apt-repository ppa:cassou/emacs

update packages

sudo apt-get update

install emacs 24.3

sudo apt-get install emacs-snapshot-el emacs-snapshot-gtk emacs-snapshot

remove old emacs

sudo apt-get autoremove

Well, first off the OP asked for emacs 24, not snapshot. Second, emacs 24 is already in his Ubuntu release. – Dirk Eddelbuettel Apr 29 '13 at 2:15
OK... How will you suggest I edit my answer? – juanitofatas Apr 29 '13 at 2:21
Well ... see my answer, and comments. I think at this point you should just delete this own-answer attempt. – Dirk Eddelbuettel Apr 29 '13 at 2:25
OK. I think we leave both answers. I am new to Linux. So dpkg, apt-cache is new to me. I need more time to study then use it. For now I will stick to simple (simple for me) solution to upgrade the emacs. Thanks! – juanitofatas Apr 29 '13 at 2:28
Well, 24.3 is not present in quantal's repository, so installing emacs24 package from ppa:cassou/emacs is probably the easiest way to get it. – immerrr Apr 29 '13 at 8:24
