I recently upgraded my operating system to Ubuntu 20.04 LTS from Ubuntu 16.04 LTS, and ported over some old Unity projects, running 2019.3.13f1. Where previously they would build to webGL format perfectly, now every attempt to build to webGL fails during the "Building Native Binary with IL2CPP" step. I've reproduced this in freshly-built projects and also installed 2019.3.14f1, same results.
I assume the issue lies in this error: "error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory"
Here's the complete error output, please send help
