Package installation error for freshly installed Linux: wait(): IOError: FDWatcher: bad file descriptor

[cihga39871]

Hi,

After a fresh installation of Ubuntu 22.04, I found Julia constantly throws an error related to downloads. It affects functionalities of numerous packages, including Plots. I intensively use Julia and Plots.jl, and hope it can fix soon.

I installed julia binary or build julia manually, the error still occurs.

I removed ~/.julia folder, and run the following commands:

Even with those errors, installation of Plots.jl will complete. However, Plots cannot pass its test (pkg> test Plots), showing the same error (FDWatcher: bad file descriptor)

What filesystem are you using for ~/.julia? It might be that your filesystem doesn't support the inotify feature.

[cihga39871]

The filesystem of ~/.julia is Ext4.

[cihga39871]

Found why. Some file downloads not complete. Is it possible to hint incompete download? Or check shasum?

[albheim]

Seems like this is the same as JuliaLang/Downloads.jl#197?
