[SOLVED] Counter Strike 2, game would not start. Creating New Namespace Failed.

Counter Strike 2, game play.

The game would not start in steam.

Eventually I saw an error in the steam diagnostics (thank the devs for that).

The last 2 lines...

pressure-vessel-wrap[2596]: E: Diagnostic output:
bwrap: Creating new namespace failed: nesting depth or /proc/sys/user/max_*_namespaces exceeded (ENOSPC)

I saw that the setting on my system was not set.
I looked at some of the other settings and presumed it needed the same range as the others.

I found it set to 0

I can insert the code required to set this parameter for the linux kernel.

echo "user.max_user_namespaces = 63505" > /etc/sysctl.d/max_user_namespaces.conf

Reboot to set the namespaces parameter.
check the list with...

sysctl -a

glenn@GamesBox ~ $ uname -a
Linux GamesBox 6.5.0-0.deb12.4-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.5.10-1~bpo12+1 (2023-11-23) x86_64 GNU/Linux

I hope this will help.

<edit>
Tested over a 1 hour playing games.
I only wonder if the figure "63505" is overkill. I'll have to find out if it was the kernel version or if I arranged for it.

Thank you

I can confirm the steam game Counter Strike 2 is running quite well with the changed settings.

Hi, Thanks for your tips, SauriNN. I'll check vpesports out.

I haven't run the game as Admin... But have verified the game files over and over again.

I found this error about "max_user_namespaces" by using steam's file and system integrity check, "diagnostics".

Not sure what bwrap (bubblewrap?) is for, a sand box or file compression?

Anyhow, I'll keep checking things.

The game runs now, although I prefer CSS where I have over a 100 maps I play offline with 22 bots (10 or 11 per side).

Thanks again.

I've encountered similar issues when running games on Linux, especially with newer kernel versions. The default settings can sometimes be too restrictive for games like CS2 that rely on sandboxing or containerization features. Setting the user namespaces value higher is a good call. However, 63505 might be overkill, so you could try scaling it down and testing different values. If you're still having trouble or notice any performance issues, keep tweaking it. Also, if you want to upgrade your CS2 skins for the next match, <USE MY SPAM LINK> for some quick and easy options.

And you're on the wrong track trying to spam. Noticed and reported.

The new ranking system in CS2 seems to put more emphasis on individual performance rather than wins, which can be a good or bad thing, depending on how you play. CSGO felt more win-based and sometimes frustrating when teammates dragged you down.

And your three fluff/bot posts have been reported.
