UPDATE: i found out that kali-core template build seems updated recently (this month) so you could try it instead , and ignore this comment.
I personally use a morphed Debian installation , i cloned Debian and upgraded it to Debian’s testing and security testing repos (Debian trixie) then finally to Kali’s repositories followed by updating and upgrading again.
This is an option if you don’t need Kali’s full graphical interface and menus , but prefer to run Kali as an App Qube with ‘seamless’ integration with Qubes OS.
This guide is similar to what i have done 
:
Note : bookworm has taken place of bullseye (bookworm is the current stable release), trixie has taken place of bookworm as the testing (next stable release) as can be found on Debian’s website at the time of this post.
So take that into consideration if you follow the linked guide

I had been using this as i faced an issue before with updating Kali that i got it from community templates back then.
