Install cron on 2.3.4: no way

[latimeria]

Hi all,
I'm trying to install cron on my 2.3.4 pfsense but it says I must upgrade to 2.4.1 before; I tried both 2.4.1 and 2.4.2 some month ago and both giving problems. Any way to keep installing packages without upgrading?
Thanks

change the update settings to stay on the 2.3 branch
