Why does the Update Installer fail with either no clear error message shown or with "File on disk does not match expected meta data" in the log file?

3 views (last 30 days)
When trying to install an update with a standalone installer, the installation process terminates with the message:
Installation failed [1]
Or if I open the installation log file, there are lines reading with
Warning: File on disk does not match expected meta data
How can I resolve this?

This usually means that the file being looked at was modified. There are a few recommended solutions to try:
  1. Uninstalling and reinstalling the affected products and then apply the update to a clean installation.
  2. Running the update as an administrator.
  3. Disabling any antivirus software.
  4. Uninstalling and reinstalling MATLAB and of its products with administrative privileges, antivirus software disabled, and then attempting the update once more.

Reinstalling is a mess. Any option to add `force` mode to the updater?
I have this issue for update 4 of R2018a on Linux. The installation of MATLAB is a folder which requires root for write permission. The only program touched those files was Update 3.
