On an aptitude system (e.g. Debian, the Ubuntus, and
so on) you don't have to bother uninstalling programs
because they are just binaries (and sometimes scripts)
that lie passively unless you invoke them: they are
put into their respective boxes in the filesystem and
do not interfere with other programs - they are also
small, so disk space shortage cannot be remedied that
way either.

The package manager is the best way to not have to
deal with the make, configure, and 'make install'
dance, and you don't have to fiddle the symlinks,
either.

Of course it is still possible to uninstall - sudo
aptitude remove - but that is mostly done (seldom)
when the upgrade/installation process has had some
dust in its machinery and you need to give it
a fresh start.

How to uninstall Emacs?

[Rodolfo Medina]

Hi all.

I recently installed Emacs after downloading it from git repositories.  Suppose
I would like to uninstall it - I want to try how the Emacs distribution
provided by Debian works and then, perhaps, reinstall Emacs from git.  How can
I completely uninstall it?

Thanks for any help.

If you compiled and built it yourself with 'make install', go to the build
directory and try 'make uninstall'.

"make uninstall", of course.  Assuming you have the source tree for
the version you want to uninstall.

Or you could simply try the Debian one without uninstalling your
version.  When you compile from git sources and 'make install' it will
install emacs into /usr/local/bin/emacs.  Since PATH includes
/usr/local/bin ahead of /usr/bin calling emacs calls your locally
compiled binary first.

To avoid this you can simply call the system packaged version
directly.  You can do this even with your locally compiled one
installed in /usr/local/bin.

  /usr/bin/emacs

Calling it specifically by that path will invoke the system packaged
version.  You can verify this by looking at the emacs version.  The
version is usually displayed near the bottom of the start up splash
screen.  If not (I customize mine away) you can ask it directly.

  M-x emacs-version

If you have customizations in your dot emacs file you can test the
stock system configuration with the -q option.  The -q option
instructs emacs not to load an init file.

  /usr/bin/emacs -q

Because of Jorge's smokescreens I got the impression
that I couldn't see the OP either, but now when I read
it this is the best answer. Mine is still correct in

Thanks to all who replied.  There was really no need to uninstall Emacs from
git to taste Emacs from Debian.  To do that, as suggested, I did:

 # aptitude install emacs24

.  Then, to start it,

 $ emacs24

; whereas, to start Emacs from git,

 $ emacs

Bye

Let me suggest this additionally.  Because of ideological differences
between two of the best free(dom) software organizations the emacs
documentation is in the non-free section.  I prefer not to rehash it
again because this has been discussed many times before.  But you want
the emacs documentation too.

  # aptitude install emacs24-common-non-dfsg

That will install the docs if you have the non-free section included
in your /etc/apt/sources.list file.  Here is an example.  You didn't
say which version you were using so I will guess Jessie by the emacs24
version.

  deb http://http.debian.net/debian jessie main contrib non-free

Additionally instead of installing "emacs24" directly it is better to
install the "emacs" package.  That will always depend upon the best
version available.  Previously it was emacs23.  In Jessie it is
emacs24.  In this way emacs is automatically upgraded.  If only
emacs24 is installed then the assumption is that you don't want to
upgrade when emacs25 becomes available.

Also I recommend to install the emacs-lisp source too.  The disk space
isn't a concern these days.  The .el files are nice to have in
addition to the compiled .elc files.  And there are some other emacs
goodies too.  Here is a full recommendation.

  # aptitude install emacs emacs24-common-non-dfsg emacs24-el emacs-goodies-el

That would be a much more fair comparison of functionalities.

Ah!  Yes.  That will work.  Since emacs24 exists as /usr/bin/emacs24
and doesn't exist in the emacs from git.  Very good.

Thanks: in my sources.list I have the non-free section:

To do so, I should now:

 # aptitude purge emacs24
 # aptitude install emacs

?  Then, what about the above emacs24-common-non-dfsg package?  Will it be also
automatically upgraded to future Emacs versions?

Oh!  You are running sid.  And using the truly global generic
ftp.debian.org alias for klecker2.snt.utwente.nl.  AFAIK that is a
single machine.  That isn't so good.

It would be better to use the http.debian.net redirector service for a
geographically dynamic redirection.  It is relatively new but has been
proving itself very useful and robust.

Additionally when running sid there are times when transitions occur
and dependent packages are removed.  It is a best practice for sid
users to also include testing too.  That way during transitions things
generally continue to be intallable.  This is just one of the things
that person running Sid Unstable is expected to know.  Because
Unstable isn't recommended for people who don't.

I recommend this for you for a generic Sid Unstable system.

  deb http://http.debian.net/debian sid main contrib non-free
  deb-src http://http.debian.net/debian sid main contrib non-free

  deb http://http.debian.net/debian testing main contrib non-free
  deb-src http://http.debian.net/debian testing main contrib non-free

> To do so, I should now:

No.  Do not purge 'emacs24' as the installation of 'emacs' would
immediately install 'emacs24' again.  That would be silly.

  emacs pulls in emacs24
   emacs24 pulls in emacs24-bin-common plus a zillion other libraries
    emacs24-bin-common pulls in emacs24-common
     emacs24-common pulls in emacsen-common

In previous days emacs pulled in emacs23 and a similar dependency
change for v23.  In the future emacs will pull in emacs25 and a
similar dependency chain for v25.

I strongly suggest that new users run one of the stable software
distribution releases.  Debian Jessie 8 is due out April 25th.  At
this point in time Jessie 8 would be the best OS version to run.
Unstable is too crazy of a place for non-combatants.  It has been
frozen for many months in preparation for release.  That lulls people
into a false sense of stability.  But immediately after the release
the floodgates on changes for Unstable are going to be open and
Unstable will once again live up to its name.

> Then, what about the above emacs24-common-non-dfsg package?  Will it be also

I don't know what aptitude does with "Suggests:" relationships.  I
don't use aptitude and am not familiar with it.  I use apt-get and I
believe that apt-get will not upgrade Suggests.  Therefore
emacs25-common-non-dfsg (emphasis on 25) will need a manual install at
that time.  But I hear that aptitude is more agressive at installing
more.  So I don't know.

Thanks.  The two last lines relatives to `testing' will be used by the system
only if the first two, relatives to `sid', should fail?

The end result is okay but it wastefully removes emacs24 and then
immediately installs it again.  'emacs24' is a dependency of the
current 'emacs'.  Why remove what will be immediately re-installed?

Maybe it was enough simply

 # aptitude install emacs

.  The reason to install `emacs' package having emacs24 already installed is
what you said above:
