Whata about the new ubuntu flavor? Will the new ubuntu mate desktop flavor competitive with? I guess ubuntu mate it very desirable by sysadmin and devops but otherwise is left from simple users.
They do not have public ISO and do not have packages in stable PPA (but have 3 packages in unstable PPA).
The discussion was last active in June.
They have 7 github repositories with interesting ubuntucinnamon-meta
package, but I do not know how to compile system from it.
So currently it is too early and hard to say without seeing UbuntuCinnamon in real action.
