It is the C library that one or more of units/libraries you are linking against require.
The issue is that you are making a binary on a newer version of glibc (the C library) than the system you want to run it - glibc (and most libraries really) is *backwards* compatible but not *forward* compatible: you can only run binaries on a system that uses the same or older versions of the library/libraries but not newer.
The solution is very simple: build the binary on the oldest version of libraries you want to support - with the easiest approach being to download an ISO of some older version of a distro that has the oldest versions you want to support. For example AppImage suggests using at most the oldest still supported version of Ubuntu (e.g. Bionic Beaver from 2018).
This is not unique to Lazarus or FPC, BTW, it is the same for any language and program that links against shared libraries on Linux.
