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/libstdc++.so.6: undefined symbol: _ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE, version GLIBCXX_3.4
