I didnât read much of this thread but the VPS might give a hint. If you are in a virtualized server and you want to modify kernel parameters the underlying host needs to allow that. Norbert

Yes, I did. I even rebooted Ubuntu.
Given that this problem occurs for both Debian and Ubuntu, there must be some commonality that hasn't been documented.

I've switched over to Ubuntu Server 18.04 LTS. I've repeated all the steps to arrive at Pharo installation. I'm still having the same problem: pthread_setschedparam failed.
Here's my /etc/security/limits.d/pharo.conf:
* hard rtprio 2 * soft rtprio 2

Bizarre. I've created a new VirtualBox image of Debian and now this solution no longer works! I'm still getting the thread priority warning. So

solution appears to be unreliable.
Why use Debian (not that it is bad, it is just a bit more technical) ?
I think you would have less problems using Ubuntu (it is just as open, it is what everybody else is using and it is much more user friendly).
<sigh>

Okay, I've resolved everything. First, the reason why I'm getting the 'pthread_setschedparam failed' error when I run Pharo under Debian is because it must be run as 'root'! Don't ask me why, but that's the reason why Pharo can't set thread priorities. (This wasn't an issue under Ubuntu Server â go figure.)
Second, I am now using Pharo's own SHA256 class. It's probably not as secure (because it doesn't use a salt value) and not as quick to execute
(not
being C code), but for my purpose, it doesn't really matter.
So I can use DigitalOcean or OVH to run my web server in a VPS.
Good to hear. But you shouldn't need to run Pharo as root, just be root to create this config file.... cat <
