Update problems: unexpected end of file error message/Download image processing toolbox

When starting the update download, the download manager stops at 3% and shows this error message:

The following error was detected while downloading

examples/images_maci64_1534954113.enc:

Unexpected end of file from server.

I tried the download several times without success. What to do next?

Please explain, how you "start the update download".

I started the download with the "InstallForMacOSX.app" retrieved from Mathworks.

I think you should give writing permission to its directory. Firstly, you have to find where your matlab is located, so write "matlabroot" to matlab's command window.

mr = matlabroot

It will give you something like this: '/Applications/MATLAB_R2017b.app'

Then after that open Mac OS X Command Line and change your directory into that and give writing permission to it, simply write the commands below.

cd /Applications/MATLAB_R2017b.app
sudo chmod o+rwx .

It will give you writing permission to this file.

Unfortunately this was not the solution.

After giving writing permission to the Applications directory, I receive this message:

usage: chmod [-fhv] [-R [-H | -L | -P]] [-a | +a | =a [i][# [ n]]] mode|entry file ...

chmod [-fhv] [-R [-H | -L | -P]] [-E | -C | -N | -i | -I] file ...

Reinhards-iMac:MATLAB_R2018b.app rk$

But the error message remains and appears after 3% of the download.

This was not the solution. Sorry, but would be grateful for new suggestions how to solve the problem.
