Upgrade Troubleshooting

This document describes methods of troubleshooting problems firewalls may encounter when attempting to run an upgrade.

Upgrade Log

pfSense-upgrade keeps a log of the last update attempt, which may contain additional useful information. This log is located at /conf/upgrade_log.latest.txt. Please include the contents of this log with any post or support request when requesting assistance with upgrade problems.

Upgrade not Offered / Library Errors

If the update system does not offer an upgrade to the most recent version, the upgrade will not proceed, or the upgrade process encounters errors with shared libraries, take the following steps:

  • Navigate to System > Updates

  • Set Branch to Latest stable version

  • Refresh the repository configuration and upgrade script by running the following commands from the console or shell:

    pkg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade

Rewrite Repository Information

In some cases the repository information may need to be rewritten:

  • Navigate to System > Updates
  • Set the Branch to Latest Development Snapshots
  • Wait for the page to refresh
  • Set the Branch to Latest stable version

If the update still does not appear, run the commands above from the console or shell.

CLI Troubleshooting

If the GUI update is not functioning as expected, there are a handful of shell commands that can help gather information or resolve problems.

Force pkg Metadata Update

Often times DNS or connectivity problems will prevent the firewall from finding updates. A quick way to verify this is to force a pkg metadata update:

pkg-static update -f

This command forces an update and will print errors if problems are found, a few potential errors include:

No address record:
 The firewall cannot resolve the update server hostname. This could be a problem with DNS from the firewall itself, or connectivity from the firewall to the Internet in general, such as a missing or incorrect default route.
No route to host:
 The firewall cannot reach the update server because it cannot find a route there. Most likely, the firewall is missing its default route or the WAN with the default route is down.
Operation timed out:
 The firewall was unable to download a file in a timely manner. This is most likely due to degraded connectivity between the firewall and the update servers. It could also be a routing issue, or a problem with IPv6 on the firewall (See IPv6 Connectivity Problems).
Authentication error:
 There is a proxy between the firewall and the update servers and it requires authentication. Move the firewall so it is not behind a proxy, or configure the proxy under System > Advanced, Miscellaneous tab.
No trusted public keys found:
 The firewall is attempting to update from the wrong repository. Ensure the correct branch is selected as mentioned in Rewrite Repository Information. May require a reinstall to resolve. For CE installations, try the following command:
fetch -qo /usr/local/share/pfSense/keys/pkg/trusted/ \

Manual Update Check

To run a manual update check from the CLI:

pfSense-upgrade -d -c

When run successfully, this command will print a line stating that a new version is available, and the version number of the available update. Errors displayed during that process are likely to be the same as those covered in Force pkg Metadata Update.

pkg.pfsense.org Has no A/AAAA Record

pkg does not use A/AAAA records. It uses service (SRV) records. The update server meta names such as pkg.pfsense.org are not meant to be accessed directly using a browser.

To find the actual update servers, lookup the SRV record for the host:

$ host -t srv _https._tcp.pkg.pfsense.org
_https._tcp.pkg.pfsense.org has SRV record 10 10 443 files01.netgate.com.
_https._tcp.pkg.pfsense.org has SRV record 10 10 443 files00.netgate.com.

$ host files01.netgate.com.
files01.netgate.com has address
files01.netgate.com has IPv6 address 2610:1c1:0:6::40

$ host files00.netgate.com.
files00.netgate.com has address
files00.netgate.com has IPv6 address 2610:1c1:0:6::41

Accessing the hosts using their real hostnames will work with a browser:

$curl --output /dev/null --silent --head --fail \
$ echo $?

IPv6 Connectivity Problems

If IPv6 is configured on the firewall, pfSense will prefer to use it when performing an update. There are cases when a firewall may have broken IPv6 connectivity, however, that contribute to problems updating. This could manifest as a timeout or routing error when upgrading.

Typically the operating system will attempt to fall back to IPv4, but the extra time this takes could also lead to a timeout.

The firewall can be configured to prefer IPv4 to eliminate this as a potential cause. See Controlling IPv6 or IPv4 Preference for details.

Alternately, from ssh or a console shell, force the upgrade to use IPv4 manually:

pfSense-upgrade -4

Forced pkg Reinstall

Forcing a reinstallation of all packages may resolve problems that otherwise may require a full reinstall. This is not ideal, as a clean install is more likely to have a positive result, but that is not always an option in every situation (e.g. remote install with no console access).

To forcefully reinstall all packages, take the following steps:

  • Make a backup

  • Clean the repository and forcefully reinstall pkg, repo data, and the upgrade script:

    pkg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade
  • Force a reinstall of everything:

    pkg-static upgrade -f
  • Review the list of changes and enter y to proceed

  • Manually reboot the firewall

Last Resort

If nothing else works then a reinstall will eliminate any possibility of problems related to the upgrade itself.

pfSense supports multiple options to easily restore the configuration. The fastest method is Recover config.xml as discussed in Automatically Restore a pfSense Configuration During Installation. Using that method, pfSense can pick up the existing configuration from the existing install and use it, eliminating the need for any manual restore process. The firewall will boot up after installation with the old settings and reinstall packages as needed.
