vagrant – Solve with SaltStack: initctl: `Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused`
Vivid now uses systemd instead of upstart.
You can try: sudo systemctl start instead.
I will post some of the contents of: https://wiki.ubuntu.com/SystemdForUpstartUsers. I ran into this problem with Ceph and used the above method to get around it.
This document compares Upstart and systemd with a view to aiding in the transition to the latter.
First, it is important to note that systemd is only fully supported in Ubuntu 15.04 and later releases. While systemd is available in prior releases through the Ubuntu repositories, there is a deemphasis of support for these releases as noted here. Hence, it is advised to use the default upstart on prior releases.
System Init Daemon
This has changed as part of the Ubuntu 15.04 devel cycle.
Ubuntu 15.04 (using Systemd by default):
Systemd runs with PID 1 as /sbin/init. Upstart runs with PID 1 as /sbin/upstart.
Prior versions (using Upstart by default):
Upstart runs with PID 1 as /sbin/init. Systemd runs with PID 1 as /lib/systemd/systemd.
Switching init systems
If you are running Ubuntu vivid (15.04), you can easily switch between upstart and systemd at will since both packages are installed at present. As of March 9 2015, vivid was changed to use systemd by default, before that upstart was the default.
Switch to upstart for a single boot
In grub, select Advanced options for Ubuntu, where you will find an Ubuntu, with Linux … (upstart) entry. This will boot with init=/sbin/upstart.
If you have upstart-sysv installed and thus boot with upstart by default, there will be an Ubuntu, with Linux … (systemd) entry, which will boot with init=/lib/systemd/systemd.
Permanent switch back to upstart
Install the upstart-sysv package, which will remove ubuntu-standard and systemd-sysv (but should not remove anything else — if it does, yell!), and run sudo update-initramfs -u. After that, grubs Advanced options menu will have a corresponding Ubuntu, with Linux … (systemd) entry where you can do an one-time boot with systemd.
If you want to switch back to systemd, install the systemd-sysv and ubuntu-standard packages.
Currently you can switch to upstart, notify the developers of the package in question of the need to support systemd.
