Same here on my Ubuntu 24.04.1:

$ sudo bpftrace
bpftrace: error while loading shared libraries: libLLVM-18.so.18.1: cannot open shared object file: No such file or directory


$ apt-show-versions | grep -i bpftrace
bpftrace:amd64/noble-updates 0.20.2-1ubuntu4.2 uptodate

Indeed problem gone after downgrading (thanks Andreas)

$ sudo apt-get install bpftrace=0.20.2-1ubuntu4
$ apt-show-versions | grep -i bpftrace
bpftrace:amd64/noble 0.20.2-1ubuntu4 upgradeable to 0.20.2-1ubuntu4.2

$ bpftrace --version
bpftrace v0.20.2

Title:
  fix underlinking with recent LLVM 18.1.8 backport

Status in bpftrace package in Ubuntu:
  New
Status in bpftrace source package in Noble:
  Fix Released

Bug description:
  An archive test rebuild with a planned LLVM 18.1.8 showed up one regression, building bpfrace.  The issue however is in bpftrace itself, and is already fixed in oracular 0.21.0-1ubuntu1.
  Another backport is from 0.21.0-1ubuntu5, ignoring the unknown .debug_addr section in dh_dwz on armhf.

  Testing done for that patch: The package builds with the backported
  18.1.8 package and passes its tests.
