  3. Start unoserver and take a conversion in diffrerent command line prompt: 
    python3 -m unoserver.server
    python3 -m unoserver.converter --convert-to pdf my.docx my.pdf
  4. If you encounter the font problem, you should add windows fonts to Linux with the following steps.
    1. Copy all fonts files under C:\Windows\Fonts
    2. Remove the .fon files
    3. Copy the font files to Linux and paste the files in /usr/share/fonts/win/. and you should create win directory by yourself.
    4. Update the font cache with the following commands in /usr/share/fonts/win/ : 
      mkfontscale
mkfontdir
fc-cache

      If you cannot find the commands, run

      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: 
    [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
