After deleting the dhcp6${UUID}-${IF}.lease file and reconnecting the
interface the "starts" timestamp is now up to date. Not sure if this is
relevant to the internals of dhclient though.
$ cat dhclient6-0775a2a6-a4a1-40bf-bd85-9c3068582dbc-wlp3s0.lease
default-duid "\000\001\000\001\036z\001X\000\037;\275t\205";
lease6 {
interface "wlp3s0";
ia-na 3b:bd:74:85 {

iaaddr 2a02:8011:2007::3 {

Title:
Failed to renew DHCPv6 lease after suspend
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
After fixing IPv6 address assignment (#1469346), IPv6 works fine until
sleep. On wake up ubuntu fails to renew its IPv6 lease:
Jan 13 10:47:47 ubuntu dhclient: PRC: Renewing lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: PRC: Rebinding lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: XMT: Rebind on wlp3s0, interval 9890ms.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed bound -> unknown
Jan 13 10:47:47 ubuntu dhclient: PRC: Address 2a02:xxxx:xxxx:xxxx::b44
depreferred.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed unknown -> expire
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): canceled DHCP
transaction, DHCP client pid 1170
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed expire -> done
I'm not sure that it's solely NetworkManager issue (dhclient could
also be affected).
