MATLAB: Do I get a “decompression failed” or “Unable to expand” error when downloading R2018b Update 4 on Mac

MATLAB

Why do I get the following errors when downloading R2018b Update 4 on Mac?

Decompression Failed

Unable to expand

Best Answer

Decompression Failed

This error occurs in Safari if the "Open Safe Files" option is on. When the download is completed, Safari will attempt to unzip the archive but return this message.

To resolve this issue; # Disable the "Open Safe Files" option in the General tab of Safari settings # Use a different browser

Unable to expand

This error occurs because Archive Utility, the Mac unzipping tool, is unable to unzip packages over 4 GB of data.

Use the following terminal commands to unzip the update zip archive to the downloads folder.

~/Downloads/R2018b_Update_<enter update #>_macOS_package.zip -d ~/Downloads/R2018b_Update_<enter update #>

MATLAB: Do I receive an error ” The conversion from UNKNOWN to NCHAR is unsupported” when working with DATAINSERT or FASTINSERT in Database Toolbox 3.10 (R2012a)

Support for inserting characters t ypes has been incorporated in Release 2012b (R2012b). For previous product releases, read below for any possible workarounds:

There is a limitation in Database Toolbox 3.10 (R2012a) in the way that it does not support nchars containing only one character.

To work around this limitation please install the attached patch:

1. Log in to an account with appropriate permissions to overwrite files in your MATLAB installation. On Linux systems, this is typically the root account.

2. Locate your MATLAB installation by typing matlabroot at the MATLAB command prompt. This folder is referred to as <MATLAB> in subsequent steps.

3. Exit MATLAB.

4. Download the attached .zip file associated with this Bug Report and store the file in the <MATLAB> folder.

5. Make a backup copy of each of the files listed in the .zip file. To see the contents of the .zip file open the .zip file in Winzip or Linux equivalent and look at the contents.

6. Extract the files from the .zip file.

a. Open the .zip file.

b. Extract the contents of the file to your <MATLAB> folder.

7. Delete the .zip file in the <MATLAB> folder.

MATLAB: Do I see a “java.lang.NullPointerException” in the installation log when trying to install a support package

The support package installation folder is not set or cannot be retrieved for some reason. The installation folder is saved in $MATLAB/toolbox/local/supportpackagerootsetting.xml. The file may not exist, not have read permissions or be invalid.

Run the following command to see if any errors are returned:

>> matlabshared.supportpkg.getSupportPackageRoot

Run the following to set an installation folder, then run the above again to verify if the folder was set properly:

>> matlabshared.supportpkg.setSupportPackageRoot('path_to_writable_location')

Replace "path_to_writable_location" with a valid path. Common locations are:

- Windows: C:\ProgramData\MATLAB\SupportPackages\<release>

- Linux: /home/<user>/Documents/MATLAB/SupportPackages/<release>

- Mac: /Users/<user>/Documents/MATLAB/SupportPackages/<release>

Alternatively, setting the contents of supportpackagerootsetting.xml to the following should work on all platforms:

<?xml version="1.0" encoding="UTF-8"?>
<SupportPackageRootSettings>
   <Setting name="sproot">__DEFAULT__</Setting>
</SupportPackageRootSettings>
