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 read "note that all limit settings are set per login."
You haven't mentioned whether you logged out and back in again?

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

no longer works! I'm still getting the thread priority warning. So

this

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 ��� 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....
