Ok, as planned I can reproduce this in local autopkgtest. Multiple hits on: AssertionError: Regex didn't match: 'inet6 2600::[0-9a-f:]+/64 scope global (?:tentative )?(?:mngtmpaddr )?(?:noprefixroute )?dynamic' not found in '14: eth42@veth42: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000\n link/ether d6:77:5c:e0:6e:89 brd ff:ff:ff:ff:ff:ff\n inet6 2600::19/128 scope global dynamic noprefixroute \n valid_lft 86399sec preferred_lft 86399sec\n inet6 2600::4d67:83f1:60b3:9385/64 scope global noprefixroute \n valid_lft forever preferred_lft forever\n inet6 fe80::892a:6b8:c86a:50a2/64 scope link noprefixroute \n valid_lft forever preferred_lft forever\n'
Due to the changes this is dynamic->forever for some, but not all, of the cases. An MP has been proposed here [1] which in local VM based autopkgtest already succeeded. @Iain/Desktop-team - would you have a look and if you agree upload that NM update?

Fine, but the same commit also did this: Alter calculation of preferred and valid times in router advertisements, so that these do not have a floor applied of the lease time in the dhcp-range if this is not explicitly specified and is merely the default. And that change is buggy and causes advertisements to have infinite lifetime, when you are using the default.
