I just found out that FreeBSD 13.2-RELEASE will be end-of-life support within 1 month time from now. It’s time to upgrade FreeBSD on one of nas boxes to 14.0-RELEASE. The following is to capture the steps used to perform the upgrade. It’s similar to my old post.

  1. SSH into the server, and run tmux or screen. You really don’t want to lose SSH connection during the upgrade.
$ ssh kenno@nas2

$ tmux
  1. Check the current running version of FreeBSD:
root@nas2:~ # freebsd-version
13.2-RELEASE-p11
  1. Make sure the system is up-to-date with all the patches:
root@nas2:~ # freebsd-update fetch
root@nas2:~ # freebsd-update install

root@nas2:~ # pkg update
root@nas2:~ # pkg upgrade
  1. Upgrade FreeBSD from 13.2 to 14.0
root@nas2:~ # freebsd-update -r 14.0-RELEASE upgrade
src component not installed, skipped

The following components of FreeBSD seem to be installed:

Does this look reasonable (y/n)? y

  1. Wait for a long while… then when the update process detects changes in some important files, I’m asked to decide what to do by editing that file, pick the desired changes, and save them. For example:
The following changes, which occurred between FreeBSD 13.2-RELEASE and                                                                       [0/143]

To install the downloaded upgrades, run "/usr/sbin/freebsd-update install".
  1. Perform the update by running the above suggested command.

Completing this upgrade requires removing old shared object files.
Please rebuild all installed 3rd party software (e.g., programs
installed from the ports tree) and then run "/usr/sbin/freebsd-update install"
again to finish installing updates.
  1. How to rebuild all installed 3rd party software? I’m guessing I need to run pkg update && pkg upgrade.
