Q:
Reading package lists... Done
Building dependency tree
Reading state information... Done
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.
A:
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
