os-isc-dhcp-1.0_3 failed to install on upgrade from 25.7

[cpw]

Thought I'd report that this package failed to automatically install as the release notes said it would, on update from 25.7.11 to 26.1.

It also fails to start and I now seem to have to configure all my old DHCP stuff into DNSmasq.

I have no idea what this BPF device is supposed to be. It seems that all the previously present config for DHCP has been removed, and the plugin fails to restore it. This is not a simple upgrade if you're using ISC DHCP and you need to warn about this mess..

EDIT: I had to restart opnsense to get the DHCP server to work... Thanks to previous poster from a few days ago who found the same problem.

Can you check the upgrade log for me?

# opnsense-update -G

Hi!

I'm seeing the same issue when upgrading to 26.1_4.

I can try to grab the upgrade log, but that means I'll have to run the upgrade again. For now I restored my VM so everything works again.

This is what I did, upgrading from the latest 25.x:

• Performed console upgrade to 26.1_4
• After the upgrade no clients received IP addresses
• The ics-dhcp service was missing from the GUI under Services
• Regular clients didn't get an address, and static mappings were not handed out
• Restarted
• Uninstalled and reinstalled the plugin, GUI shows
• Restarted again
• Regular clients finally got addresses, but static mappings still didn't work
• Reverted the VM because the family wasn't happy — devices with static assignments couldn't connect

I have a log for this and it's basically a rare but very annoying package manager bug:

As you can see the package manager stops at 172 of 173 with an error that is not supposed to happen (ENOENT). This prevents the plugin from being updated (and in this case all the isc-dhcp package files to be installed. 173 would have been the plugin. You can witness this by package version number of the plugin still at 0.1 post-upgrade, but it should be 1.0.

I'll work on this, but it's really not our corner and not of immediate interest in FreeBSD it seems as this has been going on for years.

Regular clients finally got addresses, but static mappings still didn't work

@franco if DHCP dynamic addresses worked, this means that ISC was running. But why would static mappings not work? Is this another bug that was introduced with 26.1?

This is rather important to me, because I am using ISC DHCP and a lot of static mappings as well.
