Can't get root priviliges for hyperion

Hi,

I'm trying to set root user for Hyperion.NG. I used the code below in terminal of Rapsberry Pi OS (RPI3):

sudo chmod +x /usr/share/hyperion/scripts/updateHyperionUser.sh && sudo updateHyperionUser -u root

Next I have to type 'Yes' for question:

Are you sure you want to run Hyperion under root? [Yes/No] Yes

The last line is:

Restarting Hyperion Service: hyperion@root.service

But I guess the script not worked for me because debug log in WEB UI looks like this:

2022-10-21T07:19:57.515Z [LEDDEVICE|First LED Hardware instance] (ERROR) Device disabled, device 'ws281x' signals error: 'Hyperion must run with "root" privileges for this device. Current user is: "pi"'
2022-10-21T07:21:27.598Z [LEDDEVICE|First LED Hardware instance] (ERROR) Previous line repeats 6 times
2022-10-21T07:21:27.599Z [LEDDEVICE|First LED Hardware instance] (ERROR) Device disabled. Maximum number of 6 attempts enabling the device reached. Tried for 1788836300 seconds.

Any ideas? I would like to ensure my RPI will be working with WS2812b led strip.

I have a look into script updateHyperionUser.sh in usr/share/hyperion/scripts/ and in the end it should print "Done" in terminal. But it does'nt.

When installing Hyperion, everything is prepared in such a way that you only have to enter sudo updateHyperionUser -u root

I used that command too, but effect was the same.

After first post in that thread, I tried to reinstall Hyperion (uninstall and install using commands from here), but it wasn't help.

Is there any Hyperion running you started manually before?

Yes, Hyperion is running when I'm trying to run script. I can get acces to configuration on WEB UI from RPI and another computer/smartphone in network.

But I found and used another code (with, and without letter "d"):

sudo systemctl disable --now hyperion(d)@pi

sudo systemctl enable --now hyperion(d)@root

And the ansower from terminal is:

1. Failed to disable unit: Unit file hyperion@pi.service does not exist.
2. Failed to disable unit: Unit file hyperiond@pi.service does not exist.

Code: hyperion postinst

BINSP=/usr/share/hyperion
BINTP=/usr/bin
#create symlink for updateHyperionUser.sh script
ln -fs $BINSP/scripts/updateHyperionUser.sh $BINTP/updateHyperionUser 2>/dev/null

There's no different after execute code from above.

Yes, I ran Hyperion from menu in GUI after installation. Is there a way to create service manually or force Hyperion to do it somehow?

Zitat von Lord-Grey

I guess then no service was created during installation, as service is normally for headless systems by default.

Or there is no way to do so in system with GUI?

Finally, how can I set root user for Hyperion afterall?

Zitat von pclin

Code

systemctl daemon-reload
systemctl enable hyperion@root
systemctl start hyperion@root
systemctl status hyperion@root

After execute code the terminal said:

Failed to enable unit: Unit file hyperion@root.service does not exist.

Failed to start hyperion@root.service: Unit hyperion@root.service not found.

Unit hyperion@root.service could not be found.

Futhermore I tried that code:

sudo systemctl -q enable hyperion.service --now from another thread.

The ansower from terminal was:

Failed to start hyperion.service: Unit hyperion.service has a bad unit file setting.

See system logs and 'systemctl status hyperion.service' for details.

So I ran sudo systemctl status hyperion.service and get:

I reinstalled Hyperion via SSH and command sudo updateHyperionUser -u root does the job. Thank you.
