package lib32z1-dev 1:1.2.8.dfsg-2ubuntu5 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-2ubuntu5

[L. David Baron]

While this error looks very similar to the one in bug #1512992, it happened as a result of the updates that were released today, i.e., it seems like the result of the *fix* for that bug.

Thanks for taking your time to report this issue and help making Ubuntu better.

I made a comment on bug 1512992, so hopefully someone will take a look at this in case more fixes are needed.

Status changed to 'Confirmed' because the bug affects multiple users.

[dino99 (9d9)]

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.

Reporter, is this still present on 17.10 or 16.04?
