What am I doing wrong here?

I fail to reproduce it. The error is also strange since [AbstractFFTs](https://github.com/JuliaMath/AbstractFFTs.jl) should have a version and is no dependency of [IterativeSolvers](https://github.com/JuliaLinearAlgebra/IterativeSolvers.jl/blob/master/Project.toml) and LinearAlgebra

Is that a fresh Julia directory or maybe old/manually changed/whatever?

Looks like your registry might be corrupted - try deleting your `/.julia/registries` directory and try again.

Or actually even easier do `registry rm General` followed by `registry add General`

Maybe try using a local [environment](https://pkgdocs.julialang.org/v1/environments/).

Note that this isn’t a package conflict, as the error message says there are no known versions for AbstractFFTs (not no versions within some compatibility bounds)

OTOH, I try everything when my global environment goes bonkers;)

Thanks!  
This worked!
