Untuk menebus reputasi saya, saya melakukan riset lebih lanjut dan mencoba beberapa hal dengan server saya. Setelah melakukan hal berikut ini, saya tidak lagi mendapatkan pesan kesalahan dan server saya tampaknya bersikap normal. Saya menggunakan halaman ini SystemdForUpstartUsers untuk panduan.
Apa yang saya tidak tahu, tetapi tampaknya berhasil. Saya merasa bahwa Pemula dan Systemd saling bertentangan. Dengan memaksa untuk menginstal Systemd, Upstart dihapus.
apt-get --force-yes install systemd-sysv ubuntu-standard
update-initramfs -u
di sini adalah output saya:
