Hello.
I just installed Zorin 17 and everything was going smooth. After my first reboot though I'm now getting a failed to install important system update error on every start up.
I get these details from the software manger
Detailed errors from the package manager follow:
failed to build result for a45df35ac0e948ee180fe216a5f703f32dda163f
Is there way to find out what the package is, and how to resolve this? really appreciate a response
How did you manage to upgrade considering the lack of an upgrade tool? 
Sorry for the confusion, i changed the wording. I was previously on 16.3 and just installed 17 so it was like a "upgrade" to me lol.
Ah, no worries. 
Unfortunately, I still have to switch to 17, so I cannot help you there—maybe one of the other members can chime in on your problem.
This looks like a Snap Issue in combination with the Gnome Software store.
Can you kill snapd and Software store,
killall gnome-software snapd gnome-software-plugin-snap
rm -rf ~/.cache/gnome-software
sudo apt install --reinstall fwupd gnome-software gnome-software-plugin-snap
snap refresh
Launch Gnome Software or Software updater (The update depends on Gnome Software) and test...
I have exactly the same message which started showing up on every startup after a successful BIOS update. I tried the snap refresh suggestion above, and that did not fix it. I might have a new (unwanted?) snap installation now however.

All snaps up to date.
If you do not use or want Snap, you can remove any Snap Packages that you have installed with Snap, then run
sudo apt remove --purge snapd
Do you use Flatpak Packages?
If Yes, you may need to run
flatpak update
in terminal.
flatpak update resulted in 'nothing to do'
I haven't noticed any problems, but continue to get this message on every boot.

Can you please try:
fwupdmgr refresh
fwupdmgr get-updates
This is normally related to a firmware upgrade. The firmware upgrade is OK but the error gets reported anyway.
If you search for a file containing the text <UID> in /var using grep, for example:
sudo grep -rnw /var/ -e '570d24e21cec6aadc4c7019ea2d7cfc16c22191b'
you will more than likely find /var/lib/fwupd/pending.db. Deleted this file and restart. The message will then be gone.
I cannot delete this file? delete is not an option. How do i have to fix this issue?
The /var directory is in Root so a user must elevate to root in order to delete or modify a file there.
sudo -i
Launch file manager (core or Pro)
nautilus
(Lite or Pro Lite)
thunar
Then navigate to /var/lib/fwupd/ and right click thje pending.db file to delete it.
Thanks this works perfect!
Not limited to Zorin, is actually a very widespead issue. Of no real consequence. There will be a backport eventually. Just Google the string.
Seeing this also. Zorin 17. Tried a few update, refresh commands but still happens on reboot. Will update here if I find something that works.
Hi. Im a total beginner. I see a few people saying that something worked here for them with this.
I tried the commands but this is what I got....doesn't seem to look good haha! What am I not getting right?

I think we need more information about what you are trying to solve and what you are trying to do? Do you have a error like "failed to install important system update" after every reboot? If so, the only thing you need to do is this:
sudo rm /var/lib/fwupd/pending.db
I did read all your output, and it confuses me about what you are trying to do?
