makedns command failing in Ubuntu OS with below error

[abhishek-sa1]

 ddns plugin bug, pid 481337, process description: 'xcatd SSL: makedns for root@localhost: ddns instance' with error 'Usage:  Net::DNS::RR::TSIG->create( $keyfile, @options ) at /usr/local/share/perl/5.38.2/Net/DNS/Packet.pm line 632.

TSIG: unable to sign packet at /opt/xcat/lib/perl/xCAT_plugin/ddns.pm line 1589.

I have already installed libnet-dns-perl and still facing issue.

@Obihoernchen @samveen can you help me in this?

@abhishek-sa1 would you please check on the omapi key settings? The error is usually in the case when makedns tries to update bind's configuration, but fails due to a mismatch between the omapi key configured in bind (in the main bind configuration file), versus the omapi key value in xcat passwd table.

Which Ubuntu version do you use?
Usually Ubuntu is not very well supported/maintained with xCAT.

[abhishek-sa1]

I am using Ubuntu 24.04 OS with xCAT 2.16.5 version. I am able to install xCAT in Ubuntu 24 and provision successfully with some changes... only makedns command is failing.

[Obihoernchen]

Unfortunately Ubuntu 24.04 is not supported nor tested.
The Net::DNS library of Ubuntu 24.04 is probably to new.
The backwards compatible syntax used by xCAT for Net::DNS::RR::TSIG->create was removed in Net-DNS v1.23.

@Obihoernchen

Ubuntu 22.04 libnet-dns-perl version: 1.33

Ubuntu 24.04 libnet-dns-perl version: 1.44

I am able to install xCAT successfully in ubuntu 22.04 and facing no issues. I think its due changes after 1.33 version

**** 1.36 Dec 30, 2022

	Adopt JSON as presentation notation for EDNS options.
	Disallow zero packet->id in outbound packet.
	Remove deprecated 2-argument TSIG->create() method.
	Revise TSIG test scripts and documentation.

Can i make any local changes to fix this issue?

@abhishek-sa1 possiblities that I can think of:

• You can downgrade the package back to the older version and then mark it to be kept at the old version with sudo apt-mark hold libnet-dns-perl
• It may be possible to backport the support back into the newer version of the package, but that will require you to either create a local override in '/usr/local/lib', or rebuild the package locally on every upstream version update.

@Obihoernchen Markus, Would you please create 2 tickets for tracking Ubuntu support for the LTS version of Ubuntu - 22.04 and 24.04 , even if it's not actively worked on (similar to the RHEL 9 tracker)? A central tracker would help with information coordination.

[Obihoernchen]

@abhishek-sa1 oh you are right probably a typo by me. It was removed in 1.33, not 1.23 :D
RHEL9 still uses 1.29 that's why it's working for RHEL9.

But since it is deprecated syntax either way, I would also like to merge a PR supporting the new syntax, too. This would be even better I think.
