R2018b update 3 in linux

Hi,

I run Matlab R2018b update 2 in Ubuntu 18.10, of course as a non-root user.

If I try to update to update 3, I get an error that the install directory is not writable - of course - it should ask the sudo password.

I installed update 2 by reinstalling Matlab after downloading matlab_R2018b_glnxa64.zip which contained update 2.

Now I need to do the same but the download matlab_R2018b_glnxa64.zip does not contain update 3.

Please correct both issues.

Kind regards,

Bert

Dirty trick to be able to use the matlab GUI to install update 3:

bert@Dell7577Linux:/usr/local/MATLAB$ sudo chown -R bert R2018b/
bert@Dell7577Linux:/usr/local/MATLAB$ sudo chgrp -R bert R2018b/

and after installation:

bert@Dell7577Linux:/usr/local/MATLAB$ sudo chgrp -R root R2018b/
bert@Dell7577Linux:/usr/local/MATLAB$ sudo chown -R root R2018b/
