      Shell

      apt-get install xfonts-utils

      1	apt-get install xfonts-utils

   5. You can also check the font status via fc-list
5. Create a system service for unoserver in /etc/systemd/system/unoserver.service:
   
   Shell

   [Unit] Description=unoserver After=network.target [Install] WantedBy=multi-user.target [Service] Type=simple User=root Group=root ExecStart=/usr/local/bin/unoserver Environment=PYTHONUNBUFFERED=true Restart=on-failure RestartSec=3

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

   [Unit] Description=unoserver After=network.target   [Install] WantedBy=multi-user.target   [Service] Type=simple User=root Group=root ExecStart=/usr/local/bin/unoserver Environment=PYTHONUNBUFFERED=true Restart=on-failure RestartSec=3

   
   You should also use systemctl daemon-reload to take effect. And if you want to make the service on startup, run systemctl enable daemon-reload
