Diagnose Synthetic ActiveGate installation/update failure due to missing dependencies

Missing dependencies can show up in a few different ways in the installation log. You can find clear information about the missing dependency and what you need to do to fix it. The Synthetic installer log can be found at /var/log/dynatrace/synthetic/dynatracesynthetic-install <datetimeOfInstall>.log on Linux hosts. If this file does not exist, you can check /tmp/ for any dynatracesynthetic-install <datetimeOfInstall>.log files.

Here's an example log file output when there are missing packages.
