package zlib1g-dev 1:1.2.8.dfsg-2ubuntu4 failed to install/upgrade: trying to overwrite '/usr/include/i386-linux-gnu/zconf.h', which is also in package lib32z1-dev 1:1.2.8.dfsg-2ubuntu4

[robert key]

Test Case
---------
1) Install zlib1g-dev:i386
2) Install lib32z1-dev.
3) Observe a package installation failure

After enabling -proposed you should be able to install both packages without an issue.

[Dominique Pellé (dominique-pelle)]

In case it helps someone else having the same issue, I repaired my apt-get packages using:

$ sudo apt-get -o Dpkg::Options::="--force-overwrite" install zlib1g-dev:i386

I came up with this after reading this... https://raphaelhertzog.com/2011/08/01/understanding-dpkgs-file-overwrite-error/

i have a duplicate bug, but runs in reverse:

package lib32z1-dev (not installed) failed to install/upgrade: trying to overwrite '/usr/include/i386-linux-gnu/zconf.h', which is also in package zlib1g-dev:i386 1:1.2.8.dfsg-2ubuntu4

___

and this is a FRESH install!

should i force this as:
$ sudo apt-get -o Dpkg::Options::="--force-overwrite" install lib32z1-dev
???

Thanks!

I encountered this while trying to setup an Android build environment/kernel building environment.

Forcing as mentioned above works.

[Hans Joachim Desserud (hjd)]

Based on some of the duplicate bugs, this also affects Ubuntu 16.10.

[Flávio Vivório Salles (flaviovivorio)]

Sure it affects Ubuntu 16.04. I was trying to install the wine 2.0 libs when it happened.

[Brian Murray (brian-murray)]

I managed to recreate this is a clean yakkety virtual machine by installing zlib1g-dev:i386 and then installing lib32z1-dev.

[Brian Murray (brian-murray)]

This is *not* reproducible on zesty so the packaging changes in zesty bear investigating.

[Brian Murray (brian-murray)]

Hello robert, or anyone else affected,

Accepted zlib into yakkety-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/zlib/1:1.2.8.dfsg-2ubuntu5.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Thanks for the fix. It is great to have a feedback (and a fast one). You are doing a great job.

[Robie Basak (racb)]

@Fathi

Sorry for the delay. It was caused by nobody affected coming forward to verify the proposed fixes as requested in comments 13 and 14. As Andreas has kindly stepped in to verify the fixes, I can now release the fixes to the updates pockets.

Just installed Xenial with all updates and can't install zlib1g-dev. It does not exist in proposed (tried from there) so I assume it's in the usual update repos. It looks like it is still broken. Is there a work around?

sudo apt-get -o Dpkg::Options::="--force-overwrite" install zlib1g-dev:amd64

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 zlib1g-dev : Depends: zlib1g (= 1:1.2.8.dfsg-2ubuntu4) but 1:1.2.8.dfsg-2ubuntu4.1 is to be installed
E: Unable to correct problems, you have held broken packages.

Sorry, what does this mean? I do not understand.
Looking forward to your reply.
Have a great day
