I installed Julia via miniconda conda install -c conda-forge julia.

When I tried to add IJulia, it failed to precompile.

It looks like cert.pem is missing.

I'm having the same issue. After some searching, I found a workaround: JuliaLang/MbedTLS.jl#225 (comment)

The URL there is outdated. The command I use is

sudo wget https://curl.se/ca/cacert.pem -O /usr/share/julia/cert.pem

[schlichtanders]

The same error occurred for me when using a combined Python + Julia binder docker setup
