Python 3 is recommended. This article left in place for reference only.
The D-Bus Python modules let the CrossOver application installation wizard detect the insertion of media such as CD-ROMs and USB flash drives. This lets it look for Windows installers and automatically pick the appropriate application profile.
This is not needed to run Windows applications.
On CrossOver 17 and greater, the simplest solution to fix this issue is to run: /path/to/cxoffice/bin/cxfix dbus
Or add --show-all to see how CrossOver would fix it on your platform and others.
Alternatively you may try one of the commands below.
Arch Linux : pacman -Syu python2-dbus
Debian : apt-get install python-dbus
Fedora : yum install dbus-python
openSUSE : zypper install dbus-1-python
cxfix --show-all may have more up-to-date fixes.
The commands above likely also apply to derivatives of the mentioned Linux distributions. So for instance a fix for Debian is likely also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora will likely also work on Red Hat Enterprise Linux, CentOS, etc.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
