For anyone else finding this, Node 18 (and beyond) is [built against RHEL8](https://github.com/nodejs/node/blob/main/doc/changelogs/CHANGELOG_V18.md#toolchain-and-compiler-upgrades) . The GLIB requirement isn’t backwards compatible. You’ll need to target [ubuntu 20](https://github.com/nodejs/node/blob/main/BUILDING.md#platform-list), 22 and beyond to build successfully.

Info on supported environments and how to change the default target: [The Ubuntu Linux Build Environments - Travis CI](https://docs.travis-ci.com/user/reference/linux/)
