hello

This is the first time this happens to me.

I followed, as always the instruction found in
https://wiki.trinitydesktop.org/UbuntuInstall



Everything seemed ok, but when I logged in for the first time with TDE I
received 

Cannot start kdeinit check your installation.

I run again 
sudo apt-get install kubuntu-default-settings-trinity kubuntu-desktop-trinity

but it told me everything fine.

So I will purge the installation and repeat it, but I would like to
understand the reason for this mysterious behavior.

regards
