Unable to update colorhug firmware

[Jerry Quinn]

I have a colorhug version 1 device with firmware 1.2.1. From reading, it appears that fwupd supports the colorhug firmware:

jlquinn@cerberus:~$ fwupdmgr get-devices

I've read that there is a firmware 1.2.6 that I need for this device. I ran fwupdmgr refresh, then downloaded and examined the xml file by hand. There appears to be an entry for 1.2.6 (and versions back to 1.2.2):

However, when I try to update, I get the following:

root@cerberus:~# fwupdmgr update
• ColorHug has the latest available firmware version

so for some reason, fwupdmgr believes that this firmware doesn't apply.

On the surface this seems like a bug, based on other things I've read around the net.

It seems the GUIDs do match. This seems like a peculiar bug, maybe around some other requirements that are set.

Would you mind trying to install the CAB like this:

# fwupdmgr install foo.cab

And see what the message tells you?

[Expired for fwupd (Ubuntu) because there has been no activity for 60 days.]

fwiw: `fwupdmgr install aa1b94b36c91929fbf75551b8a376d7292f8c51c-hughski-colorhug-1.2.6.cab --force` worked for me on ubuntu bionic (--force required because of version numbering issues fixed in upstream fwupd after bionic release)
