Note that it happened to other, see this comment: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1413232/comments/8 Or even an article recommending disabling apparmor for dhclient(!): https://blog.anthony-jacob.com/perte-dip-v4-sous-ubuntu-20-04-apparmor-et-dhclient/ As I said, I'm not sure this is the root cause of the lack of IPv4 renewal, because running it manually *does* succeed in getting an IP. And running it in strace shows the EACCES failure: [pid 1095210] openat(AT_FDCWD, "/proc/self/task/1095211/comm", O_RDWRstrace: Process 1095211 attached ) = -1 EACCES (Permission non accordée) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1918410/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
