fwupd Will Not Start

Hello everyone.
This is my first post so sorry if its hard to follow.

I'm trying to update my peripherals with fwupd, but the daemon does not start.
I checked its status with 

Systemd status

but I don't understand the output enough to fix the error.

Here it is:

Re: fwupd Will Not Start

Hm, works without issue here. Is the issue still present?

Also could you try to fetch the backtrace of the crash?

Re: fwupd Will Not Start

I am also having this issue. I attempted a backtrace, but no idea if I did it correctly:

What other information can I provide to help troubleshoot?

Re: fwupd Will Not Start

No the backtrace is lacking debug symbols .. Did you say yes / y when being asked about debuginfod?

No, it didn't ask me. Is there a way to force it to do that manually?

Re: fwupd Will Not Start

what's the output of "echo $DEBUGINFOD_URLS" for you?

Re: fwupd Will Not Start

DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl gdb 7943

It will always ask.

Well, I must be doing something very wrong then because it takes me straight to a (gdb) prompt and does not ask any questions.

This is the command I ran:

sudo coredumpctl gdb 20448

I also ran it as root (without sudo) but also was not asked any questions.

Re: fwupd Will Not Start

Could you try setting "set debuginfod enabled on" manually? Also if you run as root please make sure that the environment variable is really set, i.e. by running "sudo DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl gdb -1"

I really appreciate the guidance; that worked. Here is the backtrace:
