Package: ufw
Version: 0.36-7.1
Severity: important
File: /etc/init.d/ufw
Justification: renders package unusable

Hi,
ufw apparently depends on nftables but the init script does not declare it.
This results in errors from ip-tables-restore when ufw starts:
Starting firewall: ufw...

startpar: service(s) returned failre:ufw ... failed!
Adding "nftables" to the Required-Start: and Required-Stop: lines in
/etc/init.d/ufw resolves the problem:
# Required-Start: $local_fs nftables
# Required-Stop: $local_fs nftables
Thanks,
Roger
