Attempt1: Installation via App Center
I've downloaded XnViewMP-linux-x64.deb and opened with App Center, as result I've got an endlessly loading page
Attempt2: Installation via terminal
$ sudo dpkg -i XnViewMP-linux-x64.deb

When I'm trying to install dependencies I get errors:
$ sudo apt install libgdk-pixbuf2.0-0 libopenal1 libxcb-xinerama0

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libgdk-pixbuf2.0-0 : Depends: libgdk-pixbuf-xlib-2.0-0 (>= 2.40.2-3build2) but it is not going to be installed
libopenal1 : Depends: libopenal-data (= 1:1.23.1-4build1) but it is not going to be installed
Depends: libsndio7.0 (>= 1.8.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Maybe somebody know how to manage these dependencies?
Update:
BTW it helped me:
$ sudo apt --fix-broken install
