The default package environments are kept under `<homedir>/.julia/environments/<juliaversion>`. To upgrade from say `v1.7` to `v1.8`, copy `.julia/environments/v1.7/Project.toml` into `.julia/environments/v1.8/`, start a session of Julia 1.8 and do `] instantiate` to populate the manifest.

All minor versions share the same base environment, so copying the `Project.toml` in this case is not necessary.

Here is an issue for that error message [download fails with `FDWatcher: bad file descriptor (EBADF)` · Issue #197 · JuliaLang/Downloads.jl · GitHub](https://github.com/JuliaLang/Downloads.jl/issues/197)

Can you tell which package causes the error to be thrown? Then delete that from `.julia/packages/` and try to instantiate again.
