Verifying bug with
ii  bpftrace       0.21.2-1ubuntu1 amd64

$ lxc launch ubuntu-daily:oracular bpf-oo --vm
$ lxc shell bpf-oo
# bpftrace -l '*sleep*'
: CommandLine Error: Option 'debug-counter' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted

As expected.

Now, verifying the fix:

Enable proposed (omitted) and install bpftrace 0.21.2-1ubuntu1.1 from
oracular-proposed

# apt install bpftrace/oracular-proposed
...
# bpftrace -l '*sleep*'
kfunc:vmlinux:__bpf_prog_array_free_sleepable_cb
kfunc:vmlinux:__ia32_sys_clock_nanosleep
kfunc:vmlinux:__ia32_sys_clock_nanosleep_time32
kfunc:vmlinux:__ia32_sys_nanosleep
kfunc:vmlinux:__ia32_sys_nanosleep_time32
kfunc:vmlinux:__probestub_mm_compaction_kcompactd_sleep
....

As expected.
