How to uninstall a deb package

[mahesh]

some time ago I downloaded ozone.deb and installed by

> sudo apt install ozone.deb

The commercial licence worked like expected and I set a icon to the favorite bar. Now I like to uninstall this version V2.70e before upgrading to any later version. Unfortunately, the package does not appaer in the ,,installed" group of the Gnome Application Manager.


> locate ozone


shows, that the package is obviosly installed in


/opt/SEGGER/ozone


and some minor files in


/usr/share/doc/ozone



What is the prefered way to uninstall this package ?
