Unit service is not loaded properly: Exec format error. on ubuntu18.04 creating .net service

Question

I am trying to create a service to run by .net application on ubuntu 18.04.

cd /lib/systemd/system/YellowPages.service

[Unit]
Description = Yellow page         


        

Answer 1

There are a couple of issues with your daemon:

[Unit]
Description = Yellow pages .NET service

Remove spaces around equal sign:

[Unit]
Description=Yellow pages .NET service

ExecStart needs an absolute path (hence the error):

[Service]
Type=forking
WorkingDirectory=/home
ExecStart=/usr/bin/dotnet /home/yp_app/YellowPages.dll

Your dotnet executable might be located elsewhere, although you can find out its absolute path by doing:

$ which dotnet

Whatever is returned would be the absolute path to use.
