Updating FreeBSD from an Unsupported Version

2026-08-02

Open the console, type pkg install <yourfavouritepackage> and

pkg: repository FreeBSD contains packages for wrong OS version: FreeBSD:13:amd64

Ouch. I guess it's time.

Freebsd releases page lists 13.4 as way out of date with 15.1 being latest and support going down to 14.4.

# iocage stop <all jails>
# freebsd-update -r 13.5-RELEASE fetch
# freebsd-update install
# # reboot
# freebsd-update install

With iocage jails, between every minor and major update, I update all the jails as well. 13.4->14.4->15.1. Time-consuming? yes. Safe? Also yes. Smooth process, nothing broke, granted I keep things straightforward.
