- Edited
XFCE Desktop is not ready, but it needs to be in the repository for the team to move forward, do wider testing including internal test ISOs. Users should not install it unless they just want to play and know they might need to reinstall if something breaks. You will get no support for it at this stage.
EDIT:
To be clear individual applications like thunar
should be fine to install just don't expect support for trying to run XFCE desktop at this stage, we haven't made a beta ISO available and do not even have a xfce-desktop-branding
package (sets default theme etc).
