Build error in Ubuntu 20.04

[sam81]

trying to load the RDatasets package I get the following error: CodecZlib.jl is not installed properly, run Pkg.build("CodecZlib") and restart Julia. However, when I run Pkg.build("CodecZlib") I get:

   Building CodecZlib → `~/.julia/packages/CodecZlib/5t9zO/deps/build.log`
┌ Error: Error building `CodecZlib`:

This happens on Ubuntu 20.04 with Julia version:

I cannot reproduce the problem with Julia 1.4.1 on Ubuntu 20.04. Can you reproduce it even after removing the ~/.julia directory and then installing RDatasets.jl?

thanks the issue is gone after removing the old ~/.julia directory and reinstalling RDatasets, sorry for the noise. I'm closing the bug. I'll keep the old ~/.julia directory for a little while (I've just renamed, not deleted it) in case it should be useful for further investigations.
