UBUNTU下卸载东西时，出现下面的东西，怎么解决？

MATLAB interface configuration ├─────────────────────┐
│ The MATLAB interface needs to know where MATLAB is installed on this │
│ system. This can be specified as a single directory or, in case of │
│ multiple MATLAB installations, as a glob expression (any expression │
│ supported by bash, including extended pattern matching operators). │
│ │
│ If, for example, the MATLAB executable is installed in │
│ /opt/matlab76/bin/matlab, please enter "/opt/matlab76". If there are │
│ multiple MATLAB versions installed, you can enter "/opt/matlab*" or a │
│ similar expression. Only matches that really contain a MATLAB executable │
│ will be considered. Therefore, a glob expression may match more than │
│ just MATLAB installation directories without negative side effects. │
│ │
│ Location of MATLAB installation(s): │

│ /opt/matlab76____________________________________________________________ │
