Updating all OpenBSD packages with pkg_add

Using pkg_add

Keeping your systems stable and secure

Every system needs to stay up-to-date with its packages, including OpenBSD. Most OpenBSD users already use pkg_add for the installation of packages. This utility can also be used for package upgrades.

Option 1: Use /etc/installurl

Newer OpenBSD versions use the file /etc/installurl to select the mirror for pkg_add.

Option 2: PKG_PATH

The first thing to do is defining your PKG_PATH. This will usually be the address of a FTP or HTTP server, which has the latest packages available. To have this variable set every time you log in, use the file .profile in your home directory (e.g. /root/.profile). Add the full export line below:

export PKG_PATH=“http://ftp.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(arch -s)/”

Since it won’t be active the first time you added it, execute the command, so the variable PKG_PATH will be set.

Tip: use a mirror to improve your performance and reduce load on the main systems.

pkg_add

Next step is the actual execution of pkg_add. To upgrade us the -u, use the -i for interactive and -v for verbose output.
