Update Manager provides a graphical interface for updating the version of PC-BSD® and for applying security updates. This utility can be started from Control Panel or by typing pc-updategui. It can also be accessed from its icon in the system tray, if you are logged into a desktop that provides a system tray.

The status of the icon lets you determine at a glance if any of your installed applications are out-of-date, if a system update is available, or if a new version of the operating system is available. Table 7.2a summarizes the possible statuses of this icon.

Table 7.2a: Update Manager Status

Updated1.png your system is up-to-date
Working1.png the system is currently checking for updates and patches
Sysupdates1.png your operating system is out-of-date and system update(s) or patch(es) are available
Pkgupdates.png newer versions of installed applications are available
Connecterror1.png the system was unable to check for updates, meaning you should check your Internet connection
Updating.png the system is currently updating
Restart.png the system needs to restart in order for the newly installed update to take effect

If you right-click the icon, you will see the menu shown in Figure 7.2a. As seen in the menu, Update Manager will automatically track updates to software installed using either the graphical or command line equivalents of AppCafe® and Warden®.

Figure 7.2a: Right-click Menu for Update Manager
Figure 7.2b: Applying a System Update

By default, updates are checked every 24 hours or whenever you boot the system. You can check for updates at any time by selecting "Check for updates". To disable the update check when the system boots, uncheck the "Run at startup" box. To disable the pop-up message over the icon when an update becomes available, uncheck the "Display notifications" box. To remove Update Manager from the system tray, click "Quit". You can put the icon back into the tray by typing pc-systemupdatertray.

Applying a System Update (GUI Method)

Occasionally, the PC-BSD® project releases a system update which addresses a fixed security vulnerability or a bug which impacts the use of the operating system. If the update is based on a FreeBSD security advisory, the update is usually available within 24 hours of the FreeBSD security announcement. To install a system update, open Update Manager and input your password when prompted. Figure 7.2b shows an example of a system where several updates are available .

If your system is fully up-to-date, there will not be any entries in Update Manager.

Depending upon the type of update, an “Update Details” pane may or may not appear when you check the box next to the update.

To update the system, check the boxes to select the updates to install or check the “Select/Deselect All” box. Once the updates are selected, click the “Install selected updates” button. A progress bar will indicate the progress of the update.

If the update requires a reboot, you will be notified to do so after the update has been installed. If a reboot is needed, clicking the "Close" button at the informational message will not automatically reboot the system. Finish whatever you are doing and reboot the computer to finish the update process.

NOTE: System updates are one-way, meaning you cannot unapply an update once it is installed. However, PC-BSD® 10.0.2 and higher automatically creates a boot environment before applying each system update. If there is an issue with the update, reboot the system and select the entry that represents the time that update occurred. This will reboot the version of the operating system before the update was applied. For systems earlier than 10.0.2, create a manual boot environment using Boot Manager before applying any updates

Applying a System Update (CLI Method)

TrueOS® users, or those who prefer to use a command-line utility, can use pc-updatemanager, the command line equivalent to Update Manager, to apply system updates. If you type pc-updatemanager, it will show its available options:

pc-updatemanager                                                                

/usr/local/bin/pc-updatemanager - Usage ----   branches - List available system branches   chbranch <tag> - Change to new system branch   check - Check for system updates   install <tag>,<tag2> - Install system updates   pkgcheck - Check for updates to packages   pkgupdate - Install packages updates   syncconf - Update PC-BSD pkgng configuration   confcheck - Check PC-BSD pkgng configuration

  -j <jail> - Operate on the jail specified

To determine if any system updates are available, type the following command:

sudo pc-updatemanager check                                                          

Checking for FreeBSD updates... The following updates are available:


NAME: FreeBSD system update TYPE: System Update

Install: "freebsd-update fetch && freebsd-update install"

NAME: Remove fdescfs TYPE: PATCH TAG: fdesc-rollback-02132014 DETAILS: http://trac.pcbsd.org/wiki/patch-20140211-fdesc DATE: 02-13-2014 SIZE: 1Mb

To install: "pc-updatemanager install fdesc-rollback-02132014"

NAME: PKG conflict detection bug fixes TYPE: PATCH TAG: pkgng-conflict-03122014 DETAILS: http://trac.pcbsd.org/wiki/patch-20140312-updater DATE: 03-12-2014 SIZE: 1Mb

To install: "pc-updatemanager install pkgng-conflict-03122014"

This is the command line equivalent of the results seen in Figure 7.2b. Follow the instructions to install each update. For example, this will apply the "Remove fdescfs" patch:

sudo pc-updatemanager install fdesc-rollback-02132014

DOWNLOADING: fdesc-rollback-02132014 /usr/local/tmp/patch-fdesc-rollback-02132014.t100% of 312 B 14 kBps 00m00s DOWNLOADFINISHED: fdesc-rollback-02132014 Creating new boot-environment... GRUB configuration updated successfully Created successfully Pruning old boot-environments... TOTALSTEPS: 3 SETSTEPS: 1 umount: /dev/fd: not a file system root directory SETSTEPS: 3

INSTALLFINISHED: fdesc-rollback-02132014

Note that a boot environment is created before the patch is applied as this system is running 10.0.2.

Upgrading from 9.x to 10.x

DANGER!  IMPORTANT--README! 
  • PC-BSD® has switched to ZFS-only. This means that you can not upgrade a system that is either 32-bit or formatted with UFS. If the hardware supports 64-bit, you will need to backup your important data to another system or external drive and then perform a new installation. The new installation will perform a format of the selected disk(s) with ZFS.
  • The boot loader and default ZFS layout has changed to support boot environments and ZFS snapshot management with Life Preserver. For this reason, we recommend that you backup your important data to another system or external drive and then perform a new installation which will create the required ZFS layout.

Upgrading from 10.x to 10.0.2 (GUI Method)

Before performing an operating system upgrade, always back up the data that is important to you. Life Preserver can be used to send a system backup to a remote system.

Figure 7.2c: Upgrading the Operating System

Before attempting an upgrade, you should also be aware of the following caveats:

  • the temporary files used by the upgrade process require 2GB of free space in /usr/. If you receive an error message indicating that you do not have enough free space to perform the upgrade, you will need to delete some files or move them elsewhere in order to create enough free space.
  • an upgrade will preserve the data in the home directories, any installed PBIs, and user accounts. It also preserves common configuration files and will merge any customizations you have made into the new versions of the following files: boot/loader.conf, /etc/rc.conf, and /etc/sysctl.conf.

Once you have backed up your data and confirmed that your version of PC-BSD® is older than July 23, you can use Update Manager to upgrade the operating system. In the example shown in Figure 7.2c, a system upgrade to 10.0-RELEASE is available.

NOTE: If a RELEASE has been announced but the update does not appear in Update Manager, make sure that any updates that do show are applied first. That way, the system will be fully patched and ready for the system upgrade.

To perform the upgrade, check the box for the "System Upgrade" entry and click the "Install selected updates" button. A progress bar will indicate the download status of the files that changed with the upgrade.

Once the downloads are finished and applied, Update Manager will indicate that the system is fully updated. Close any applications that you have open, then reboot in order to load the latest version of the operating system.

Upgrading 10.x to 10.0.2 (CLI Method)

Users who prefer to upgrade the operating system from the command line can use pc-updatemanager instead of the graphical Update Manager.

Once a new RELEASE has been announced, it should appear as available using the following command:

pc-updatemanager check                                            

The following updates are available: ------------------------------------ NAME: System Update to 10.0-RELEASE TYPE: SYSUPDATE TAG: fbsd-10.0-RELEASE VERSION: 10.0-RELEASE

To install: "pc-updatemanager install fbsd-10.0-RELEASE"

To start the upgrade, follow the "To install" instructions. Messages will indicate the status of the upgrade.

Once the upgrade is complete, a message will indicate that you need to reboot the system in order for the changes to take effect. Close any applications that you have open, then type reboot in order to load the latest version of the operating system and finish the upgrade.
