I can relate to your situation, though I only have 2 kids.
I'm debating upgrading the Ubuntu 18.04 system that they use for Minecraft.
I totally understand sun-setting support for old unsupported software, but Ubuntu 18.04 is still receiving regular support. Was there a notice that we (this group) missed that development was removing support for glibc 2.27? As of right now, the Minecraft: Java Edition system requirements [https://www.minecraft.net/en-us/get-minecraft] states, "Linux: Any modern 64-bit distributions from 2014 onwards". If that is changing, please make sure to post it like the dropped support for older MacOS versions [https://help.minecraft.net/hc/en-us/articles/4420326353933-Minecraft-Java-Edition-Versions-and-MacOS-] in Minecraft: Java Edition 1.18
