Public bug reported: Hello,
Let's first list my configuration items: * apache2 2.4.29-1ubuntu4.14 * release: Ubuntu 18.04.5 LTS Upon reboot, the following message is seen in apache2.service logs: -- Unit apache2.service has begun starting up. Oct 14 12:18:32 SERVER apachectl[3833]: (99)Cannot assign requested address: AH00072: make_sock: could not bind to address [REDACTED IPV6.33]:443 Oct 14 12:18:32 SERVER apachectl[3833]: no listening sockets available, shutting down Oct 14 12:18:32 SERVER apachectl[3833]: AH00015: Unable to open logs Oct 14 12:18:32 SERVER apachectl[3833]: Action 'start' failed.

Oct 14 12:18:33 SERVER systemd[1]: Failed to start The Apache HTTP Server. The apache2 configuration is using the ipv4 and ipv6 present on the server: /etc/apache2/ports.conf:Listen <REDACTED ipv4.245>:443 /etc/apache2/ports.conf:Listen <REDACTED ipv4.247>:443 /etc/apache2/ports.conf:Listen [REDACTED IPV6::33]:443 /etc/apache2/ports.conf:Listen [REDACTED IPV6::35]:443 and the /etc/network/interfaces look as this (no netplan): # Additional IPs that are used to serve https traffic for # releases.ubuntu.com so that archive doesn't respond on 443. auto bond0:1 iface bond0:1 inet static address <REDACTED IPV4>.247/32 # Using up/down to avoid LP:1347246. up /sbin/ip addr add REDACTED IPV6::33/128 dev $IFACE preferred_lft 0 down /bin/ip addr del REDACTED IPV6::33/128 dev $IFACE preferred_lft 0 # Additional IPs that are used to serve *.clouds.archive.ubuntu.com # with HTTPProtocolOptions unsafe, which is needed to work around # cloud-init bug LP:1868232 (cRT#125271). auto bond0:2 iface bond0:2 inet static address <REDACTED IPV4>.245/32 # Using up/down to avoid LP:1347246. up /sbin/ip addr add REDACTED IPV6::35/128 dev $IFACE preferred_lft 0 down /bin/ip addr del REDACTED IPV6::35/128 dev $IFACE preferred_lft 0 I was surprised that the apache2.service does not contain a After=network-online.target $ systemctl show apache2.service | grep -E '(Wants|Require|After|Before)' RemainAfterExit=no Requires=system.slice sysinit.target -.mount Before=multi-user.target shutdown.target After=basic.target sysinit.target systemd-journald.socket system.slice network.target nss-lookup.target systemd-tmpfiles-setup.service remote-fs.target -.mount RequiresMountsFor=/var/tmp /tmp $ systemctl show network.target | grep "^After" After=network-pre.target ifup@bond0.service ifup@ens2f0.service ifup@ens2f1.service systemd-resolved.service ufw.service networking.service systemd-networkd.service So I was wondering if the "ifup@bond0" was enough as a dependency here, to be sure to have the ipv6 up and running or if we would need something like "ifup@bond0:2" and "ifup@bond0:1" as part of the list of the services in the network.target "After" list. ** Affects: apache2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899852 Title: Cannot assign requested address: AH00072: make_sock: could not bind to address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1899852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
