The command pavucontrol returns an error message:error while loading shared libraries: libgtkmm-3.0.so-1: cannot open object file: No such file or directory.
Where can I find this missing file?I checked apt-get install libgtkmm-3.0-1 The response was latest version installed.
I tried apt-cache search libgtkmm-3.0.so.1 Nothing was found.
