How to use systemd instead upstart?

Question

Suddenly systemctl stopped to work while I ssh'ed in my remote server to check service status. Output was

Failed to list units: Launch helper exited with unknown return code 1

I discovered that now upstart is used (after a couple of reboots trying to make systemctl work).

Can I use systemd as my main init again? I didn't found any info how to switch from upstart to systemd here.

Ubuntu 16.04.5.

@GunnarHjalmarsson hmm, have'nt until now. Can I upgrade without breaking my webservers and so on? I found [this question](https://askubuntu.com/questions/779544/upgrade-ubuntu-16-04-without-losing-data) so far — Tarasovych, May 09 '19 at 12:21
Don't know what version of Ubuntu your using but did you see this on that link you provided? `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.` — George Udosen, May 09 '19 at 12:26
@Tarasovych: Nobody can guarantee that you won't need to tweak a thing or two to adapt to updated software. The upside is that you get an Ubuntu version which lasts until 2023 instead of 2021, and systemd is there by default. — Gunnar Hjalmarsson, May 09 '19 at 12:27
@GeorgeUdosen "Don't know what version of Ubuntu your using" - last line of my question :) — Tarasovych, May 09 '19 at 12:27

Thanks to George Udosen, I found this article.

I edited /etc/default/grub - added init=/bin/systemd to GRUB_CMDLINE_LINUX_DEFAULT, than restarted the server sudo shutdown -r now
