I have the problem too. After the dhcp lease is expired the avahi-daemon or something else doesn't renew the dhcp lease. It helps to request an ip address manually:
# sudo dhclient <network interface> sudo dhclient enp3s0 Configure the lease time on your dhcp server to 86400 seconds (one day) and it should help the most of us to work without problems for a day. But it doesn't solve the problem. ** Changed in: avahi (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1586528 Title: Avahi-daemon withdraws address record To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1586528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
