Bug Description
Package: dhcpcd5
Version: 6.11.5-0ubuntu1
Release: artful
dhcpcd5 in artful is outputting repeated messages about adding/deleting ipv6 default routes. I didn't check other releases.
The actual log is not the problem, but the actual behavior seems to be: I don't expect dhcpcd to be adding a default route only to then instantly remove it.
The only similar issue I could find was this one:
https:/
but the solution presented there (removing the route manually) does not work on this case.
I found nothing in dhcpcd bug tracking tool at https:/
Copy & paste from syslog:
