Error while deploying

[RoyGRad]

Hi, I'm getting this error while deploying the cluster no matter what I try. Can you assist, please? Those it affects the cluster efficiency in any way?

Hi @RoyGRad !

please show what you have specified in vars/system.yml

sysctl_conf variable

Yes, you can ignore it, but I would like to understand the reason for the error

In my case it works (ubuntu 22.04)

Hi Vitaly,

I'm running it on Ubuntu 20.04. Here is the system.yml

system.txt

[vitabaks]

at first glance, the variables are specified correctly

if you don't use iptables, I recommend commenting out the "net.netfilter.nf_conntrack_max" parameter

See commit a911cb56c6680c25b7b0cc2c08033ccacb4b6a07

please provide information for debugging
