Through including various packages I somehow managed to get the warnings

```julia
WARNING: Method definition setindex(AbstractArray{T, 2} where T, Any, Int64, Int64)

overwritten in module ArrayInterface at /home/user/.julia/packages/ArrayInterface/R0AhD/src/ArrayInterface.jl:188.

```

I also have the feeling that they might cause a bug in my program, so I would like to resolve them - how do I do that?

Please post your `versioninfo()` and a larger section of your code that produces this error.  
Are you changing environments in your program at some point?

```julia-auto
julia> versioninfo()
Julia Version 1.7.2
Commit bf53498635 (2022-02-06 15:21 UTC)
Platform Info:
  OS: Linux (x86_64-pc-linux-gnu)
  CPU: AMD Ryzen 7 5800H with Radeon Graphics
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-12.0.1 (ORCJIT, znver3)

```

For the code: This happens when I included a package (let’s call it FOO for the moment) from `.julia/dev/FOO` via

`using FOO`

Interestingly, with the package `FOO` there come some examples, also using the package without the warnings popping up.

Recently, I added another package to the dependencies of `FOO` and updated the `Project.toml` file via `Pkg`. Still, the “built-in” example programs run, while my custom one gives the warnings.

# Solution: Calling

```julia-auto
pkg> update

```

Seems to have solved the issue.

Try upgrading. I think Octavian wasn’t updated in awhile so it was blocking some packages and causing a few warnings here and there. You should get v0.3.14 [Release v0.3.14 · JuliaLinearAlgebra/Octavian.jl · GitHub](https://github.com/JuliaLinearAlgebra/Octavian.jl/releases/tag/v0.3.14) and I assume that was the issue? If not, I’ll need to see `]st -m`.

Probably, `] st -m` showed that Octavian is now version `0.3.14`.

solved it, so yeah I guess that was the reason.
