Messed up libc 2.17 and libc 2.15 dependency error on 12.04LTS

I got myself into a mess in order to solve a libc dependency issue. I downloaded libc6_2.17-0ubuntu5_amd64.deb and libc6-dev_2.17-0ubuntu5_amd64.deb from somewhere and then used dpkg to install it. From then on, the nightmare starts. Anyway, here are the relevant output:

Don't bother with trying to install 2.17.

You need to re-install the specific versions of the libraries from 12.04 to fix the issue. Do the following:

 sudo apt-get install --reinstall libc6=2.15-0ubuntu10.12 libc6-dev=2.15-0ubuntu10.12 sudo apt-get -f install 

This should resolve the issue.

You could solve issue by downgrade libc6

$ apt-get install --reinstall libc6=2.15-0ubuntu10.15 libc6-dev=2.15-0ubuntu10.15 $ apt-get check 

If you met the similar error of Bill Z, please try following commands

$ mkdir -p /var/backup/usr/share/doc/libc6/ $ mv /usr/share/doc/libc6/* /var/backup/usr/share/doc/libc6/ $ apt-get install --reinstall libc6=2.15-0ubuntu10.15 libc6-dev=2.15-0ubuntu10.15 $ apt-get check $ apt-get -f install
