Known issues
It is a known issue that the installer sometimes has issues with installing the python libraries. This will result in a rather red screen.
When that happens, the only solution is to re-run the installer once more after the installation. It will then re-install the software and update the missing part due to the previous error
When a new version is installed, the software will auto detect that and will run its upgrade steps. Which is also a database update. Most database updates are fast, but when there is a new X.Y.0 release, the database will do a cleanup. That will take a long time and during that time, the software is not running and waiting to complete.
Indication: 1.8GB database takes about 20 minutes to clean up.
A warning message is shown in the console.
