The ipset package is missing from the 2026.6.1 appliance

If you use my fail2ban package on the 2026.6.1 appliance, you will see these errors in the log:
firewalld[53739]: ERROR: '/sbin/iptables-restore -w -n' failed: iptables-restore v1.8.11 (nf_tables): Set f2b-nginx-botsearch doesn't exist.

The ipset package is missing.

The ipset package is missing. Installing it resolves the issue:
zypper install ipset

Then restart fail2ban and firewalld:

systemctl stop fail2ban
systemctl restart firewalld
systemctl start fail2ban

Running ipset list should now show some output.
ipset list

This resolves the issue.
