For the frontEnd, we are using our own copy of the PHP binary (fpm). To keep that binary up-to-date, i-MSCP hooks into dpkg(1). That means that each time a package is being updated on your system, the i-MSCP /usr/local/sbin/imscp-dpkg-post-invoke.pl script is invoked. That script executes the dpkgPostInvokeTasks() methods that are implemented by the i-MSCP servers and packages.

In your case, it seem that the dpkgPostInvokeTasks() method that is implemented by the FrontEnd package installer has failed. Please provide us with the content from the /var/log/imscp/imscp-dpkg-post-invoke.log file. On success, it should contain something like:
