Why does the Update Installer fail with no clear error message shown in the log file?

When trying to install the R2017b Updates the installation process terminates with the message:

Installation failed [1]

There is no other clear indicator of what may be causing the issue. How can I resolve the issue?

If the updater installation log file does not show any clear indicator of what is causing the issue, you will want to do a search for "skipping" in the log file.

For example, in several cases there are mentions of the Simulink Real Time Toolbox being skipped:

Need to update: toolbox/slrt/target/kernel/XXXXX
Warning: File on disk does not match expected meta data
Warning:   meta size: 1526446 meta time: 1503595432 (orig)
Warning:   meta size: 1526449 meta time: 1512792246 (new)
Warning:   disk size: 1527326 disk time: 1521632126
Warning:   Skipping update

These usually means that the file being looked at was modified. The recommended solution to this is to reinstall the toolbox and then apply the update to a clean installation.

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.

I think your Linux Scripts aren't robust enough. Is there an option to "Force Update" without caring about the file touch date?
Hello Royi,
Currently there is not, I am forwarding this request internally for future reference though.
