I am trying to install slurm on Ubuntu PC. Therefore, I followed the instructions given over here I did the following - 1. sudo apt update -y 2. sudo apt install slurmd slurmctld -y 3. mkdir sudo /etc/slurm-llnl FYI... I came up with step 3. by myself 4. sudo chmod 777 /etc/slurm-llnl

sudo cat  /etc/slurm-llnl/slurm.conf

6. sudo systemctl start slurmctld 7. sudo systemctl start slurmd Now, when I do this - 8. sudo scontrol update nodename=localhost state=idle I get the error -

scontrol: error: resolve_ctls_from_dns_srv: res_nsearch error: Unknown host
scontrol: error: fetch_config: DNS SRV lookup failed
scontrol: error: _establish_config_source: failed to fetch config
scontrol: fatal: Could not establish a configuration source

**Edit 1** - I followed the instructions given by Pau. Now, I get the following outputs -
