I did:

```julia
(@v1.6) pkg> add BPFnative
[..]
  [856f044c] ↓ MKL_jll v2021.1.1+1 ⇒ v2020.2.254+0
  [da04e1cc] ↑ MPI v0.16.1 ⇒ v0.17.1

```

and even with it, I think, installed before to the same version, I got lots of upgrades for other packages, and one downgrade. At least the latter seems bad, and it’s even a totally unrelated package.

Usually doing something like:

```julia
(@v1.6) pkg> add MKL_jll@v2021.1.1+1
ERROR: ArgumentError: invalid version range: "v2021.1.1+1"
Stacktrace:
  [1] Pkg.Types.VersionRange(s::String)
[..]

```

would have fixed the downgrade, but it doesn’t like the “+1”, even though it’s a valid Julia version number. Is that a bug in Julia?

How would you fix this?

```julia
(@v1.6) pkg> add MKL_jll@v2021.1.1

The stacktrace from the resolver tells you that `MKL_jll@v2021.1.1` depends on `LazyArtifacts` but `LazyArtifacts` has not declared compatibility with Julia version 1.6.0. I would just stick with 1.5 in the meantime.

By the way, you can use `pkg> add --preserve=all Foo` if you want to avoid changes to your existing dependency graph ([12. API Reference · Pkg.jl](https://pkgdocs.julialang.org/v1.5/api/#Pkg.add)). Or you can use the `compat` section ([6. Compatibility · Pkg.jl](https://pkgdocs.julialang.org/v1.5/compatibility/)) or `pin` to prevent changes to specific packages.
