package libc6-dev-i386 (not installed) failed to install/upgrade: trying to overwrite '/usr/include/fpu_control.h', which is also in package libc6-dev-amd64:i386 2.23-0ubuntu9

[UbuntuUser009]

I ran sudo apt-get --fix-broken install
and got this:

Errors were encountered while processing:
 /var/cache/apt/archives/libc6-dev-i386_2.23-0ubuntu10_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Description: Ubuntu 16.04.3 LTS
Release: 16.04

I expected it to fix my video card driver issue with my new Supermicro X9DAi-O motherboard and other issue with it.

What happened is I got the above errors.

There are some complex relationships in biarch libc dev packages that are a bit tough to represent in a "don't do that" way. This is one of them.

The real question here is why would you have libc-dev-amd64:i386 installed on an amd64 system? libc6-dev:amd64 is effectively the same thing, but without the weird indirection of using a foreign architecture's biarch build.

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