My latop has Ubuntu 18.04.1
The Nautilus (Files browser) stop working after recent software updates ( I believe it contains some updates to Nautilus).
I tried remove and install the Nautilus, just won't fix the issue.
I tried to launch it from Terminal window by typing 'nautilus' , the error message is:
nautilus: symbol lookup error: /usr/lib/x86_64-linux-gnu/libexempi.so.3: undefined symbol: _ZN16WAVE_MetaHandler9kRIFFiXMLE
