I have no idea what has gone wrong here. I have installed the audiotool sox, then tried to install the library libsox-fmt-all and all of a sudden apt-get refused to work. I cannot use it now, neither to update nor to install anything. Could somebody suggest what i could do to get it back to work? Here is the complete message it throws:

apt-get: symbol lookup error: /usr/lib/ undefined symbol: _ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE, version GLIBCXX_3.4

It's possible that your apt somehow got corrupted.

You could try manually downloading the apt for 8.04 from the ubuntu package website and installing it with sudo dpkg -i filename_of_the_package.deb
