Can't reload '/usr/loca​l/MATLAB/R​2017b/bin/​glnxa64/li​bmwcoder_t​ypes.so'

When I try to run this code example:

f = imread('cameraman.tif');

[findex,map]=rgb2ind(cat(3,f,f,f),10,'nodither');

ff=ind2gray(findex,map);

I get this error message:

"

Also, sometimes I get this error message when I press "Ctrl+C" to copy some text:

"

I am using Matlab 2017b on Kubuntu 19.04

Any help?

Thanks in advance...
