kestrel-hellomvc.service: Failed at step USER spawning /usr/bin/dotnet: No such process

Question

I was following the tutorial https://learn.microsoft.com/en-us/aspnet/core/publishing/linuxproduction on publishing asp.net core project on Nginx, the previous steps all seem successful, but while

systemctl start kestrel-hellomvc.service
systemctl status kestrel-hellomvc.service

I got

kestrel-hellomvc.service - Example .NET Web API Application running on Ubuntu
   
Loaded: loaded (/etc/systemd/system/kestrel-hellomvc.service; enabled; vendor preset: enabled)

Apr 24 03:12:42 instance-5 systemd[1]: kestrel-hellomvc.service: Failed with result 'exit-code'.

Does anyone know the solution, it seems I don't have the /usr/bin/dotnet folder.

I've solved the problem, the source folder owner should be www-data, having 755 permission. The Apache user is called www-data on Ubuntu, and apache on CentOS. So specifically set User=www-data in kestrel-hellomvc.service if running on Ubuntu, thanks to Jeppe's comment.

Also, if you have added users in /etc/systemd/system/gunicorn.service before, removing these users might resolve this issue as well.

The Apache user is called `www-data` on Ubuntu, and `apache` on CentOS. So specifically set `User=www-data` in `kestrel-hellomvc.service` if running on Ubuntu. – Jeppe Mar 29 '19 at 19:02
I run on Centos, changing from `www-data` to `apache` works for me. – Trần Thanh Phong Sep 03 '22 at 03:13

In file /etc/systemd/system/gunicorn.service, I had added user. The issue got resolved when I removed the user.

...

[Service]
User="someuser"
...

Default user is `root` FWIW :) – rogerdpack Jan 11 '22 at 16:37

After many hours, the answer for me was "yum reinstall systemd"

Worked for me, got the error when using journalctl -xe – Omari Victor Omosa Sep 23 '21 at 22:31
Did this install a newer version perhaps? An update? – rogerdpack Jan 11 '22 at 16:37

The same error message will be displayed if the user defined in your service file does not exist, regardless of the permission on the web app folder.

This is it! If you copy and paste generic `.service` files remember to update the `User=...` in `[Service]` section. Thanks. – Tomasz Gandor Jan 17 '18 at 10:31
