Summary

A happy news gotten.
OpenBSD has released 6.6 (What's New), the new one 😊

It's become by far simpler thanks to also new sysupgrade!
Almost all what is necessary for upgrading is to run several commands.

Here is a set of the commands to run:

# syspatch
# # Here, sysupgrade will come.
# sysupgrade
# # Here, your remote connection will be closed and you will have to wait minutes.
# sysmerge
# # Confirmation will appear in case you have some configuration in such as `login.conf` and `smtpd.conf`.
# pkg_add -u
# # Finished without "Files to remove".
# # Be careful about the output which sometimes includes important information.
Enter fullscreen mode Exit fullscreen mode

Be careful about the packages you have added or configured; Make sure all of the changes are compatible with yours.

Description

1. syspatch

sysupgrade comes via syspatch:

# syspatch
...
Get/Verify syspatch65-012_sysupgr... 100% |**************************************| 11482       00:00    
Installing patch 012_sysupgrade
...
Enter fullscreen mode Exit fullscreen mode

2. sysupgrade

Remember your connection will be closed soon after running sysupgrade if you use SSH:

# sysupgrade
...
Connection to xxx.xxx.xxx.xxx closed by remote host.
Connection to xxx.xxx.xxx.xxx closed.
Enter fullscreen mode Exit fullscreen mode

In this case, you may not either connect again via SSH. Don't panic. It's because the installation is in progress. Use VNC or something else to check it. Wait minutes, so you will be able to connet perfectly again.

Well, the whole output was:

# sysupgrade

Verifying sets.
Upgrading.
Connection to xxx.xxx.xxx.xxx closed by remote host.
Connection to xxx.xxx.xxx.xxx closed.
Enter fullscreen mode Exit fullscreen mode

Connect to the server if necessary after the installation is completed and the system reboots.

3. sysmerge

The output was nothing this time:

# sysmerge
Enter fullscreen mode Exit fullscreen mode

Confirmation with the diffβˆ’like results will appear in case you have some configuration in such as login.conf and smtpd.conf.
At the confirmation:

  • "d" means to keep the existing file; The older version's wins.
  • "i" means the existing file will be overwritten; The newer version's wins.
  • "m" means to merge them.

4. pkg_add -u

You had better check "Special packages" beforehand.

So many packages were updated/upgraded as usual.
Be careful about the output which sometimes includes important information.
You will sometimes see such a message:

You should also check /etc/php-7.3.ini (which was modified)
Enter fullscreen mode Exit fullscreen mode

You can find examples for the latest version in the directories such as /usr/local/share/examples, /etc/examples/ and /var/www/roundcubemail/config.
