I'm experiencing the following problem.
I was asked from the system to update to 14.04 version of Ubuntu and I confirmed it. While it was working, the installation was giving few errors and continuing but suddenly it stopped. I cannot remember what it was installing and maybe I did a mistake but I killed the process. Now to restart the installation I googled it and found people saying simply to update and upgrade the system. But now when I give the command:
sudo apt-get update
I get the follwoing error:
apt-get: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.17' not found (required by /usr/lib/x86_64-linux-gnu/libstdc++.so.6)
I don't want to destroy my computer and I have important files. How can I face this problem? I could also back to the previous Ubuntu version but I don't know if how to do it safely.
Please give me an help!
