I am a regular Linux system user. In Linux (especially CentOS), I am used to applying updates a few times a week using yum command, but how do I do that on my OpenBSD severer? How do I apply updates on OpenBSD operating system?OpenBSD is just like Linux. However, it does not use the yum command. It depends on upon a tool called pkg_add. You can use pkg_add to apply updates or install new packages in binary format. There are three ways to keep your OpenBSD based packages, kernel and base system up to date. The first method requires applying patches and compiling the software. The second method depends on 3rd party to apply kernel and binary package patches. The third method uses the syspatch command. I recommend using 3rd method for OpenBSD version 6.1 and above users.
Method #1: Keeping your OpenBSD 6.2 up to date using source code
First download source code for OpenBSD 6.2. cd command, enter:
Step 1: Grab the source code
# cd /usr/src
Setup OpenBSD mirror to use and version number for ease of use:# BASE='http://mirror.esc7.net/pub/OpenBSD'
# VER='6.2'
Now grab the source code for both the OpenBSD userland/base system and kernel, using ftp command, run:# ftp ${BASE}/${VER}/src.tar.gz
${BASE}/${VER}/sys.tar.gz
${BASE}/${VER}/SHA256.sig
Sample outputs:
Step 2: Verify downloaded files:
Use the signify command:# signify -C -p /etc/signify/openbsd-62-base.pub -x SHA256.sig src.tar.gz
# signify -C -p /etc/signify/openbsd-62-base.pub -x SHA256.sig sys.tar.gz
Sample outputs:
Untar the tarballs using the tar command:# tar zxf src.tar.gz
# tar zxf sys.tar.gz
## [ delete file using rm command ##
# rm SHA256.sig *.tar.gz
# ls
Sample outputs:
Step 3: Grab the errata for OpenBSD stable 6.2
Download the 6.1 errata patches and apply it. In this example, I’m going to fetch a tar.gz file containing all the 6.2 version patches:# cd /tmp
# ftp https://ftp.openbsd.org/pub/OpenBSD/patches/6.2.tar.gz
Again untar all patches:# tar -zxf 6.2.tar.gz
See all patches:# cd /tmp/6.2/common/
# ls
Sample outputs:
So I have total 25 patches for my freshly installed OpenBSD 6.2 server.
Step 4: Apply the patch (kernel and base system) one-by-one:
Let us start with 001_sshd.patch.sig patch file. You need to type the following command to see the errata/path info:# more 001_sshd.patch.sig
Sample outputs:
You can apply patch by doing:# signify -Vep /etc/signify/openbsd-59-base.pub -x 001_sshd.patch.sig
-m - (cd /usr/src && patch -p0)
Sample outputs:
And then rebuild and install patched sshd:# cd /usr/src/usr.bin/ssh
# make obj && make depend && make && make install
You may have to reboot the system for kernel updates. Please note that each errata patch will have different information on how to apply and install the patch, so you need to read them carefully using more command. You need to repeat this procedure for all patches. I suggest you subscribe to OpenBSD announce mailing list to get info about the errata. You need to repeat the procedure for rest of all of downloaded patches.
Step 5: Upgrade all 3rd party packages
Synthesia code generator. Simply type the following pkg_add command:# export PKG_PATH=ftp://mirror.planetunix.net/pub/OpenBSD/`uname -r`/packages/`machine -a`/
# pkg_add -Uuv
See this page for more info.
Method #2: Keeping your OpenBSD 5.9 up to date using binary patches mode (3rd party)
Here is some info on M:Tier:
Keeping your installed OpenBSD packages up to date is hard and time-consuming. Nobody wants to read the mailing lists to spot security fixes and/or updates never mind wanting to build new packages from their ports tree and manually install them on each of their servers and/or desktops.
For this reason M:Tier is launching a new package repository which includes the latest security fixes and critical updates for OpenBSD since 5.3
It’s easy to setup and even easier to maintain…you don’t need to do anything anymore. M:Tier will even notify you by e-mail if there’s an update available (unless you opt-out).
Say hello to openup from mtier
You can use openup command. It is a small utility for OpenBSD that can be run standalone and that checks for security updates in both packages and the base system. openup uses the regular pkg tools, it does not implement anything on top. You need to trust mtier and openup maintainers to use this command. This command act like ‘yum update’ or ‘apt-get upgrade’ command. First, step is to grab the openup:# cd /root
# ftp https://stable.mtier.org/openup
# chmod +x openup
Run it to update your system including packages:# ./openup
Sample outputs from freshly installed OpenBSD 5.9 system:
Here is another example. In this case I’m running openup on freshly upgraded OpenBSD from 5.9 to 6.0:# /root/openup
> Checking for openup update
> Downloading and installing public key
> Removing old release binpatch entries
> Installing/updating binpatch(es)

Please note that M:Tier offers two service levels:
- LTS: binpatches, LTS package updates and support for the two most recent releases
- free: binpatches and stable packages for the most recent release
See this page for more info on openup and its paid and free services.
Method #3: Keeping your OpenBSD 6.1 server up to date using syspatch method on amd64/i386
OpenBSD version 6.1 comes with the syspatch command to fetch, verify, install and revert OpenBSD binary patches for base system. This is now recommended method for all OpenBSD users.
Apply all patches
Type the following command:$ doas syspatch
Sample outputs:
To see available patches, run:
$ doas syspatch -c
Sample outputs:
To see all installed patches, run:
$ doas syspatch -l
Sample outputs:
To revert the most recently installed patch, run:
$ doas syspatch -r
Sample outputs:
How to update all apps
Type the following command:$ doas pkg_add -Uuv
Sample outputs:
For more info see syspatch man page:$ man syspatch
$ man pkg_add
