Hi @ThomasSmith, welcome to the Qubes forum!
That’s really unfortunate and I was not aware that ransom campaigns were already targetting linux desktop computers as well - good to know! Qubes’ security model would have prevented that ransomware, or at least contained it to only one qube (compartment).
Installing Software on Qubes = Installing Software on Linux
Since the Qubes (Virtual Machines) are basically all linux based (debian, fedora, whonix, archlinux), installing sofware on Qubes is almost the same as installing it on Qubes. So any software compatible with those distribution should have no problem installing on qubes. And since you’re already in the linux world, it shouldn’t be too big of a jump, though you’ll have to read through the docs.
Understanding how Qubes works takes a bit of time. I suggest you watch this youtube video by explaining computers on Qubes.
But I have two extra disclaimers for you
1. The use of 3D and Video software
All Qubes software runs on virtual machines, meaning it may be a bit slower and the hardware acceleration is not there. Specifically for video productivity tools and 3D like blender, it might be a compromise you’re not willing to make.
Installing other OSes on Qubes
I don’t know here if you’re referring to installing Kodachi on Qubes as a standalone. But just in case you’re thinking of the the former, I’d suggest you drop that idea for now. (note I’m not too familiar with Kodachi)
Installing other OSes on Qubes will loose out on all the Qubes integrations (that make it actually usable). Those alre only for people willing it make new TemplateVMs. Otherwise you’ll just end end up very frustrated like this guy.
