[Bug 1479826] Re: 'systemctl enable apache2' wrongly reports a failure because of update-rc.d backwards compat actions
Looks to me like this is more likely a problem in systemd-sysv-generator than apache2 itself. ** Package changed: apache2 (Ubuntu) => systemd (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in Ubuntu. https://bugs.launchpad.net/bugs/1479826 Title: 'systemctl enable apache2' wrongly reports a failure because of update-rc.d backwards compat actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1479826/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1478849] [NEW] infinite loop in /usr/share/mysql/mysql-systemd-start causes non-interactive installations to fail/hang
Public bug reported:
# lsb_release -rd
Description:Ubuntu 15.04
Release:15.04
# apt-cache policy mysql-server-5.6
mysql-server-5.6:
Installed: 5.6.24-0ubuntu2
Candidate: 5.6.24-0ubuntu2
Version table:
*** 5.6.24-0ubuntu2 0
500 http://archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages
100 /var/lib/dpkg/status
# Problem description
When installing mysql-server-5.6 with DEBIAN_FRONTEND=noninteractive
(which is done e.g. by Puppet, SaltStack and other config management
tools), the installation will fail as not only files will be deployed to
the filesystem, but also an attempt to start the (unconfigured) service
is made.
Running the following command can be used to reproduce the issue on
Ubuntu 15.04 here:
DEBIAN_FRONTEND=noninteractive apt-get -q -y -o DPkg::Options::=--force-
confold -o DPkg::Options::=--force-confdef install mysql-server-5.6
The result is that the service start (run as StartExecPost=) hangs for
quite a while in the endless loop in /usr/share/mysql/mysql-systemd-
start:
pinger () {
while /bin/true ; do
sleep 1
mysqladmin ping /dev/null 21 break
done
}
After a while of nothing happening, systemd decides it had enough of it,
kills the script and reports a service startup failure.

[Bug 1435709] Re: mysql.service fail to start after upgrade to mysql-server.5.6
Would it probably make sense to backport the systemd-related improvements [1] from 5.7 to 5.6. Although they're not perfect yet, they're a huge improvement compared to the current hacks required to make mysqld behave more or less sane in systemd environments.

[Bug 1478849] Re: infinite loop in /usr/share/mysql/mysql-systemd-start causes non-interactive installations to fail/hang
I dug a bit deeper and it turned out the problem here is caused by port 3306 already being occupied by another local test-container and therefore mysqld aborting on startup. So in the end, the problem could be reduced to: when mysqld fails to start (as defined in ExecStart=), the 'mysqladmin ping' loop should behave a bit more intelligent instead of pinging to nowhere. If it is doable, backporting the systemd related improvements in MySQL [1] would solve this problem and also get rid of all those hacks to make MySQL 5.6 work with systemd.
