Hi Andy

I try yesterday but I got an error.

On line 15 :

tibo@RevPi134126:~/temp_lvrt24_arm64$ sudo dpkg -i lvrt24-schroot_24.1.0-3_arm64 .deb

Do you have an idea?

Hi,

The labview service runs the lvrt application inside the schroot.

It is started by the  .deb installation. 

Please can you post the output from 

sudo systemctl status labview.service

and 

ls /srv

Hi,

Thanks for all the information.

I think the error is because the file /etc/services is missing on your system. I was able to recreate the error by renaming the file on my system.

Please can you enter the following command and reboot your system.

sudo touch /etc/services

Please can you post the output from the following commands

sudo systemctl status labview.service

(Press q to exit the display) and enter the command

ps -Af | grep lvrt
