Since iptables 1.8.4-1 compat symlink /sbin/iptables does
not exist any more, so the ufw always fails:
# strace -e trace=execve -ff ufw status
execve("/usr/sbin/ufw", ["ufw", "status"], 0x7fff9d7faa10 /* 9 vars */) = 0
strace: Process 5805 attached
[pid 5805] execve("/sbin/iptables", ["/sbin/iptables", "-V"], 0x7ffec7a8b2c8
/* 9 vars */) = -1 ENOENT (No such file or directory)
[pid 5805] +++ exited with 255 +++
--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=5805, si_uid=0,
si_status=255, si_utime=0, si_stime=0} ---
ERROR: Couldn't determine iptables version

Please update to use /usr/sbin/iptables instead.
