I suspect /usr/share/emacs/site-lisp/subdirs.el doesn’t belong in emacs26-common.

[kelleyk]

Thank you for reporting an issue!

The problem here is slightly more complicated than that, but yes, this file's location creates a conflict. The Debian-maintained emacs packages relocate these files so that multiple major versions can be installed side-by-side. I intend to update my packaging at some point (when I have the time) to mirror what the Debian packages do, which should resolve this problem.

This is the same issue described in #1.

Sorry for the trouble! (I'd be happy to accept patches resolving the issue, if you or anyone else is feeling motivated.)

I am encountering the same issue. Does anyone have a work around?

[sdrafahl]

I am also getting this error

I got various conflicts when installing on 19.10 on top of the ubuntu package. But I rather uninstall the ubuntu package to have this and its module support. Thanks!

[kelleyk]

Yes: you need to either install my packages (emacs26 or emacs26-nox, which will also pull in emacs26-common and emacs26-el) or the ones from the main Ubuntu repositories. They are not interchangeable/compatible.

I'm not aware that there's really a reason to mix and match, though. Perhaps when I revisit the packaging to fix #1, I should also add Conflicts metadata so that the Ubuntu packages are removed if you try to install mine.

I removed the emacs and emacs-common packages that come with Ubuntu 20.04. After adding your ppa, successfully, I'm running into a similar (maybe same?) problem in Ubuntu-20.04 installing emacs26 and emacs26-common. I've tried various things like clearing apt cache, and other things that haven't worked, or enabled me to get past this...

@kelleyk: I'm not aware that there's really a reason to mix and match, though.

I ran into a similar problem, not intentionally trying to "mix and match". This happened when I had your package installed and attempted sudo apt install elpa-elpy, which I think tries to install emacs as a dependency from the main Ubuntu repositories! Does that make sense?

Now, with broken apt, when I try sudo apt --fix-broken install, here is the result:

@saeedghsh Thanks for the additional context! All of the packages you have there are Ubuntu ones (not from my PPA). Makes sense that they'd be pulled in by elpa-elpy.

I haven't ever tried to install Debian-packaged versions of Emacs packages like elpy; I use Emacs itself to install from ELPA/MELPA directly. Still, what you're doing should ideally not cause problems like the ones you've run into.

Let's open a tracking issue (#11). Emacs 27.1 is hopefully going to be available soon, and there are some other improvements I'd like to make to the packaging (like fixing the issues with having multiple Emacs versions installed side-by-side).

[kelleyk]

In my emacs27 packaging, I've added Provides to the control file; so, for example, apt should believe that the emacs27-common package from my PPA provides emacs-common, avoiding this problem.

Please let me know if you run into any more trouble once you have a chance to try those packages (which should be available in the PPA shortly)!

[BJSchmidt]

@kelleyk FYI I installed Emacs27 on Ubuntu 20.04 from your PPA today, and ran into the same issue:

Errors were encountered while processing:
 /tmp/apt-dpkg-install-RVK8CA/064-emacs27-common_27.1~1.git86d8d76aa3-kk2+20.04_all.deb

I was able to resolve it with:

sudo apt --purge remove emacs-common
sudo apt --fix-broken install

[kelleyk]

Hm, I'm sorry; I guess that I didn't fix that issue as well as I thought I had. I've opened #16 to track.

[improve100]

i fix the probram,flow this:
sudo apt --purge remove emacs27
sudo apt --purge remove emacs
sudo apt --purge remove emacs-common
sudo apt --fix-broken install
sudo apt autoremove
sudo apt install emacs27
emacs --version

[togakangaroo]

I seem to be getting errors no matter which of the above remediations I try

$ sudo apt --purge remove emacs-common
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'emacs-common' is not installed, so not removed
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 emacs-bin-common : Depends: emacs-common (= 1:26.3+1-1ubuntu2)
 emacs-el : Depends: emacs-common (= 1:26.3+1-1ubuntu2)
 emacs-gtk : Depends: emacs-common (= 1:26.3+1-1ubuntu2)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I'm running out of ideas as this happens no matter what I attempt to remove/add or anything. Pretty much always

dpkg: error processing archive /var/cache/apt/archives/emacs-common_1%3a26.3+1-1ubuntu2_all.deb (--unpack):
 trying to overwrite '/usr/include/emacs-module.h', which is also in package emacs27-common 27.1~1.git86d8d76aa3-kk2+20.04

Anything else to try? I'm not even sure how to uninstall anymore since even running remove emacs27 ends in the same error

[KhalfaniW]

Try removing all the packages at once to break the cycle of not being able to uninstall things.

sudo apt --purge remove emacs25 emacs [or whatever other packages that have unmet dependencies]

This got me out of the apt --fix-broken install loop

You save my life. Thank you.
