i solved opening a ticket here: https://www.teamviewer.com/en/support/#submitTicket

yeah, i cant understand how is it possible to do wrong invoice..... EU exists since 2001....

logon is always hard after I've changed account, also in windows teamviewer is no more automatic logon and I've to logon every time

no, i've not solved, but i've not tried any more i think it's something related with dm: lightdm/gdm etc, some works, others not

retry "apt-get -f install" to check everything is ok

i've found this package: https://packages.debian.org/stretch/libjpeg62-turbo maybe it can help you libpng is from debian8, i think it's a problem to install it

use gdebi, it installs all you need

me too with Ubuntu 16.04 Gnome and gdm3 i login, and then black screen with lightdm it works
