Hi Guix, I would like to run a Jupyter notebook using Julia, so I need to install the IJulia backend: guix install julia julia # Enter julia REPL ] # To go into the julia pkg REPL add IJulia # Now type backspace to go to julia REPL using IJulia This produces the error: [ Info: Precompiling IJulia [7073ff75-c697-5162-941a-fcdaad2a7d2a] ERROR: LoadError: InitError: SystemError: opening file "/gnu/store/npj8z0g9nx14wl22yphqfs2c5w4qk5jk-julia-1.8.3/share/julia/cert.pem": No such file or directory The full error message is here: https://pastebin.com/qC8yyHXT I saw a very similar bug on Gentoo: Without this file (which can be a symbolic link to `/etc/ssl/certs/ca-certificates.crt`) many Julia 1.8.3 packages, e.g. `HTTP`, do not work. This is what happens: julia> import HTTP [ Info: Precompiling HTTP [cd3eb016-35fb-5094-929b-558a96fad6f3] ERROR: LoadError: InitError: SystemError: opening file "/usr/share/julia/cert.pem": (https://bugs.gentoo.org/888978) Any help would be greatly appreciated.
