unix_process_priority: -20 gets PermissionError: [Errno 13] Permission denied

Hi. I am installed newest version of Swar Chia Plot Manager and tried to put maximum priority to plotting jobs on my Ubuntu by setting the value to -20, but I've got this error while starting the manager:

2021-05-28 11:48:21 [INFO]: Setting priority level: -20
Traceback (most recent call last):

    return cext_posix.setpriority(self.pid, value)

During handling of the above exception, another exception occurred:

Setting value to 0 solved the error, but I still want to put maximum value to plotting jobs. Thanks.

The user you are using in Linux probably doesn't have the required permissions to modify the priority of that task.

The user you are using in Linux probably doesn't have the required permissions to modify the priority of that task.

This user is the only user in the system and has root privileges. But thank you, I'll check it and write here if it works.

Try this: run at -15 sudo python manager.py restart (if that doesnt work "su -" then "python manager.py restart") make sure root has a .chia folder in their home dir with the private keys added.

Thank you, I will try it shortly. Will come back if problem solved.

Try this: run at -15 sudo python manager.py restart (if that doesnt work "su -" then "python manager.py restart") make sure root has a .chia folder in their home dir with the private keys added.

So, su - was not working at first giving su: authentication failure. To fix that, I set up password for root by sudo passwd root. Then, I could cd Swar directory and restart the manager. I set -20 and didn't get any error. Will check if it really works when manager will start a new job.

Thank you so much!

P.S. sudo python manager.py restart don't work at all and requires to make a lot of things to make it happen. Giving password to root and then execute under root is much easier.

The manager under root is not starting up the new jobs at all. I have double checked it.

The same problem！

Kill manager. kill ALL chia processes. reboot. then start chia farmer as root. make sure to copy your .chia to /root/.chia before anything you might have to export your mnemonic key then import it running either Sudo on every command OR preferably su - then as root, start the manager.
