For anyone looking to install the latest version of CrossOver on one of the best Linux distros, openSUSE Tumbleweed (I know, I know), here is what worked for me. Disclaimer: I understand that you probably don't need all of these packages. This is the result of hours of trial and error. The end result is that CrossOver installs successfully and Microsoft Office 365 works beautifully.
1) Run this command:
sudo zypper install gstreamer32 libdrm python3-gobject gobject-introspection girl libdrm python-gobject typelib-1_0-Gtk-3_0 python-xml libcapi20-3-32bit fontconfig-32bit libgphoto2-6-32bit libgsm1-32bit liblcms2-2-32bit libopenal1-32bit libOSMesa9-32bit sane-backends-32bit libXcomposite1-32bit libXinerama1-32bit libxslt1-32bit libXxf86vm1-32bit libgphoto2-6-32bit libudev1-32bit libxshmfence1-32bit libefl1 libglvnd-32bit liblcms2-2-32bit libnss_nis2-32bit libpciaccess0-32bit libxcb-dri3-0-32bit libxcb-glx0-32bit libxcb-present0-32bit libxcb-sync1-32bit libcups2-32bit gtk3 python3-gobject wine gstreamer-plugins-bad gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-ugly nss-mdns-32bit libgphoto2-6-32bit openal-soft-devel-32bit sane-backends-32bit libxslt1-32bit libnsl2-32bit libnsl2 gstreamer-32bit
2) Download and install CrossOver Linux 19.0.0 (Generic Shell Installer, Ubuntu 12.04 and earlier), not the RPM <-- you are welcome to try the RPM, I just didn't use it.
3) run this command: /home/user/cxoffice/bin/cxfix --auto
Enjoy!
