But when I get DHCPv6 address for interface deletion, script execution error occurs
Closed, ResolvedPublicBUG


However, when I get DHCPv6 address for interface deletion, a script execution error occurs. The operation sequence is:

vyos@vyos# set interfaces bridge br1 address dhcpv6 
vyos@vyos# commit
vyos@vyos# delete interfaces bridge br1 address dhcpv6 
vyos@vyos# commit


[ interfaces bridge br1 ]
start-stop-daemon: --start needs --exec or --startas
Try 'start-stop-daemon --help' for more information.
VyOS had an issue completing a command.
