My personal noble system installed bpftrace 0.20.2-1ubuntu4.2 and it
presented this bug.

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

I then updated to 0.20.2-1ubuntu4.3 from noble-proposed and bpftrace now
works:

$ sudo bpftrace 2>&1 | head -n 2
USAGE:
    bpftrace [options] filename

and:
andreas@nsnx2:~$ sudo bpftrace -e 'kprobe:do_nanosleep { printf("%d 
sleeping\n", pid); }'
Attaching 1 probe...
2997 sleeping
2997 sleeping
2997 sleeping
2997 sleeping
2997 sleeping
2997 sleeping
2971 sleeping
2971 sleeping
^C

$ apt-cache policy bpftrace
bpftrace:
  Installed: 0.20.2-1ubuntu4.3
  Candidate: 0.20.2-1ubuntu4.3
  Version table:
 *** 0.20.2-1ubuntu4.3 100
        100 http://br.archive.ubuntu.com/ubuntu noble-proposed/main amd64 
Packages
        100 /var/lib/dpkg/status
     0.20.2-1ubuntu4 500
        500 http://br.archive.ubuntu.com/ubuntu noble/main amd64 Packages


I then proceeded to spawn a noble fresh vm. There I got bpftrace 
0.20.2-1ubuntu4, which is working fine:
ubuntu@n-bpftrace:~$ apt-cache policy bpftrace
bpftrace:
  Installed: 0.20.2-1ubuntu4
  Candidate: 0.20.2-1ubuntu4
  Version table:
 *** 0.20.2-1ubuntu4 500
        500 http://br.archive.ubuntu.com/ubuntu noble/main amd64 Packages
        100 /var/lib/dpkg/status

ubuntu@n-bpftrace:~$ sudo bpftrace 2>&1|head -n 2
USAGE:
    bpftrace [options] filename


ubuntu@n-bpftrace:~$ sudo bpftrace -e 'kprobe:do_nanosleep { printf("%d 
sleeping\n", pid); }'
Attaching 1 probe...
441 sleeping
366 sleeping
^C

I then upgraded to the version in noble-proposed:
ubuntu@n-bpftrace:~$ apt-cache policy bpftrace
bpftrace:
  Installed: 0.20.2-1ubuntu4.3
  Candidate: 0.20.2-1ubuntu4.3
  Version table:
 *** 0.20.2-1ubuntu4.3 100
        100 http://br.archive.ubuntu.com/ubuntu noble-proposed/main amd64 
Packages
        100 /var/lib/dpkg/status
     0.20.2-1ubuntu4 500
        500 http://br.archive.ubuntu.com/ubuntu noble/main amd64 Packages

And it continues to work:
ubuntu@n-bpftrace:~$ sudo bpftrace 2>&1|head -n 2
USAGE:
    bpftrace [options] filename
ubuntu@n-bpftrace:~$ sudo bpftrace -e 'kprobe:do_nanosleep { printf("%d 
sleeping\n", pid); }'
Attaching 1 probe...
366 sleeping
366 sleeping
^C

And for the record, this is the llvm-18 version on both systems where I
conducted this test:

$ apt-cache policy libllvm18
libllvm18:
  Installed: 1:18.1.3-1ubuntu1
  Candidate: 1:18.1.3-1ubuntu1
  Version table:
 *** 1:18.1.3-1ubuntu1 500
        500 http://br.archive.ubuntu.com/ubuntu noble-updates/main amd64 
Packages
        100 /var/lib/dpkg/status
     1:18.1.3-1 500
        500 http://br.archive.ubuntu.com/ubuntu noble/main amd64 Packages
