I wanted to upgrade the unetbootin package this morning. It was going well until I got this error.

You might want to run 'apt-get -f install' to correct these.

The following packages have unmet dependencies:

 libc6 : Breaks: libc6:i386 (!= 2.17-0ubuntu5) but 2.17-0ubuntu5.1 is installed

 libc6:i386 : Breaks: libc6 (!= 2.17-0ubuntu5.1) but 2.17-0ubuntu5 is installed

 libc6-dbg : Depends: libc6 (= 2.17-0ubuntu5.1) but 2.17-0ubuntu5 is installed

 libc6-dev : Depends: libc6 (= 2.17-0ubuntu5.1) but 2.17-0ubuntu5 is installed

             Depends: libc-dev-bin (= 2.17-0ubuntu5.1)

 libc6-dev:i386 : Depends: libc-dev-bin:i386 (= 2.17-0ubuntu5.1)

                  Recommends: gcc:i386 but it is not installed or

                              c-compiler:i386

 libc6-i386 : Depends: libc6 (= 2.17-0ubuntu5.1) but 2.17-0ubuntu5 is installed

 libc6-x32 : Depends: libc6 (= 2.17-0ubuntu5.1) but 2.17-0ubuntu5 is installed

E: Unmet dependencies. Try using -f.

So I did tried the suggested apt-get -f install

But that resulted in the following error

The following packages were automatically installed and are no longer required:

  linux-headers-3.2.0-31 linux-headers-3.2.0-31-generic linux-headers-3.8.0-19

  linux-headers-3.8.0-19-generic python-central

Use 'apt-get autoremove' to remove them.

The following extra packages will be installed:

  libc-dev-bin libc6

Suggested packages:

  glibc-doc

The following packages will be upgraded:

  libc-dev-bin libc6

Preparing to replace libc6:amd64 2.17-0ubuntu5 (using .../libc6_2.17-0ubuntu5.1_amd64.deb) ...



A copy of the C library was found in an unexpected directory:

  '/lib/x86_64-linux-gnu/libc-2.15.so'

It is not safe to upgrade the C library in this situation;

please remove that copy of the C library or get it out of

'/lib/x86_64-linux-gnu' and try again.

Errors were encountered while processing:

 /var/cache/apt/archives/libc6_2.17-0ubuntu5.1_amd64.deb

E: Sub-process /usr/bin/dpkg returned an error code (1)

I've tried
apt-get clean
apt-get update && apt-get upgrade

But that didn't help either. The same errors are occurring. I'm a little uncertain as to whether I dare to reboot. How do I fix this?

First of all go here /lib/x86_64-linux-gnu
move these files to /root: libc-2.17.so libdl-2.17.so libm-2.17.so libpthread-2.17.so librt-2.17.so

Commands to go into the directory /lib/x86_64-linux-gnu and copy the files to /root,

sudo -s

cd /lib/x86_64-linux-gnu

cp libc-2.17.so /root

cp libdl-2.17.so /root

cp libm-2.17.so /root

cp libpthread-2.17.so /root

cp librt-2.17.so /root

Then you need to launch bash with predefined LD_PRELOAD:

LD_PRELOAD=/root/libc-2.17.so:/root/libdl-2.17.so:/root/libm-2.17.so:/root/libpthread-2.17.so:/root/librt-2.17.so bash

Commands to remove the files in /lib/x86_64-linux-gnu directory,

rm libc-2.17.so

rm libdl-2.17.so

rm libm-2.17.so

rm libpthread-2.17.so

rm librt-2.17.so

after that dist-upgrade or fix-missing package will works:

apt-get -f install

OR

apt-get -f dist-upgrade
