was just now trying to install the protonmail bridge bets, which is to allow existing email clients to work with protonmail. but the .deb install failed for lack of a litany of qt5 dependencies. i have a bunch of qt4 things installed and they seem to work alongside tde perfectly well. so i sought to install qt5-essentials, the first of the dependencies. after which -- i typically install packages from the commandline -- i got this unhappy display:

Use 'apt-get autoremove' to remove them.

oh, and it also deleted xorg, though i quickly reinstalled that. 

i'm hoping to make everyone play nice together, but before i do that i hope to back out of whatever i've gotten myself into, lest the machine surprise me at next reboot.

help!!
