Didn't I write that? And it came from 
deb http://mirror.ppa.trinitydesktop.org/trinity-sb buster deps-r14
main-r14

Wiki.trinity.desktop.org:
"TDE will automatically execute a script which will migrate as many of
your KDE3/TDE3.5.x settings as possible. At the end of the process,
your KDE3/TDE3.5.x profile will still exist (unchanged) and a new TDE
profile will have been created inside the ~/.trinity folder."
Nowhere is stated, that TDE and KDE can not coexist!

Any more suggestions?
Regards.
