Vivado 2022.1 installation gets stuck at ‘Generating installed device list’

Just like Lukas Prokop, I ran into an issue installing Vivado 2022.1 on Ubuntu 22.04. The error looks just like in their article: https://lukas-prokop.at/articles/2021-02-02-vivado-install-stuck

His article gives a recipe to fix 2018.1 version but it's not exactly fit for 2022.1, though an underlying issue is probably the same. Fix is very similar as well, and I'm trying to give more generalized approach.

Fix

The idea is to fix LD_LIBRARY_PATH environment varible for commands the installer runs.

val aNumTry = Try(BigDecimal(a))
val bNumTry = Try(BigDecimal(b))
