Are any commonly used desktop distros debian based besides Ubuntu ? Ubuntu derivatives are not as they follow the latest upstream packages 1:1 usually iirc. Monjaro has its own dependency update schedule so it creates a new userspace dependency set to build against. If 10 distros follow the same thing we have 10 different timestamps of arch you have to build against.

Maybe my info is out of date, I just use arch & fedora.

Soon we will have forks of arch forks and each one will have a completely different set of dependencies depending on when the owners decide to freeze the package. Then someone will use it and wonder why theirs so many bugs

thankfully so
