libgtkada2-bin : trying to overwrite `/usr/bin/gdialog', which is also in package zenity

Thanks for your report. Confirmed in Intrepid.

Still an issue in Jaunty (libgtkada2-bin 2.12.0-2ubuntu1)

Same for me in Jaunty alpha 3:

Preparing to replace zenity 2.24.0-0ubuntu1 (using .../zenity_2.24.1-0ubuntu1_i386.deb) ...
Unpacking replacement zenity ...
dpkg: error processing /var/cache/apt/archives/zenity_2.24.1-0ubuntu1_i386.deb (--unpack):
 trying to overwrite `/usr/bin/gdialog', which is also in package libgtkada2-bin
dpkg-deb: subprocess paste killed by signal (Broken pipe)

Debian have 'fixed' this by making zenity and libgtkada2-bin conflict; however this means that libgtkada2-bin cannot be installed without removing zenity, which is needed by several packages that are part of the normal Ubuntu install. I'm not sure what the differences are between the zenity gdialog and the libgtkada gdialog, but assuming they are equivalent, perhaps gdialog could be removed from libgtkada and a dependency on zenity added instead?

Thanks for reminding me of the existance of this bug Trim ^^. I use a self-compiled version for gtkada since then where i removed gdialog from the build (At least I don't use it). I looked into what you suggested, but it seems that gdialog_ada provides a very small subset of what zenity provides. So not only the commands are different, the syntax is different as well. Looking at gdialog_zenity it's a perl script that's supposed to convert something. I don't know perl so that's all I found out. What I'm curious about is why gdialog_ada was called gdialog2 back in hardy so libgtkada2-bin could be installed with zenity without a problem.
Another thing I noticed Is that the zenity guys don't seem to have noticed that this bug exists so I'll add a bug for zentiy here. If they can't come up with a solution on their side they should at least add a conflict on libgtkada2-bin.

The attached debdiff is against the latest debian packge, 2.12.0-3.

This fixes the conflict with zenity by no longer installing a symlink in /usr/bin/gdialog, and patching gate to call gdialog2 directly.

The latest debian package also fixes LP: #280503.

Note: the updated package builds successfully in pbuilder, and installs alongside zenity without problems.

Updated patch against latest Ubuntu package 2.12.0-3ubuntu1.

Please can someone sponsor this update in karmic.

the current zenity version uses a conflicts there

Having a conflict resolves the packaging error, but it doesn't make libgtkada2 usable since zenity is a dependency of several core Ubuntu packages, e.g. ubuntu-desktop, metacity. Therefore I think it is more reasonable to resolve this by removing the gdialog symlink from the libgtkada2 package as per the debdiff attached above. As far as I am aware there are no other packages that depend on the existence of libgtkada2's gdialog, so this should not cause any breakage.

Afaik the "fix" for zenity comes from debian unstable. So now both packages need the conflicts removed and gtkada needs Mike's fixes.

Yay, fixed in svn XD

Rename gdialog executable to gtkada-dialog.
This avoids a conflict with the gdialog binary provided by Zenity on GNOME
systems. See the following bug reports for more information:
 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497464
 https://bugs.launchpad.net/bugs/280188
Contributed by Michael Trim.

This is now fixed in 2.12.0-4 in Debian unstable.

Merged in Ubuntu

libgtkada2-bin:
  Installed: 2.12.0-4ubuntu1
  Candidate: 2.12.0-4ubuntu1
  Version table:
 *** 2.12.0-4ubuntu1 0
        500 http://archive.ubuntu.com karmic/universe Packages
        100 /var/lib/dpkg/status

Now zenity needs the conflict on libgtkada2-bin removed.

Please update the intrepid and jaunty libgtkada2 packages to the version in karmic (2.12.0-4ubuntu1). This will fix this bug and bug #280503. This has no impact as the original package version remains the same and in any case the current package version cannot be installed on most GNOME systems due to this bug.

Greetings,

I've just cooked up a debdiff backporting the conflicts/replaces fixes from Debian. Attached for sponsorship.

This bug was fixed in the package zenity - 2.28.0-0ubuntu2

---------------
zenity (2.28.0-0ubuntu2) karmic; urgency=low

  * debian/control: Version conflicts/replaces on libgtkada2-bin to
    (<< 2.12.0-4) as per Debian. There was a file conflict between zenity
    and libgtkada2 which was resolved in this version in Debian and Ubuntu.
    (LP: #280188)
