Subiquity crashes installing Ubuntu 24.04?

Got a crash when hitting the "Install recommended proprietary software" screen in the installer. This is a System76 Thelio, fresh install of 24.04 from a fresh iso. Debug logs below:

flutter: DEBUG subiquity_client: ==> setSource(ubuntu-mate-desktop) null

This happens whether I have both boxes checked or not. Additionally, I have a confirmed working good internet connection.

Any guidance is appreciated!

Hi, @surfrock66 :slight_smile:

I suggest that you report the problem that you are having - with the Ubuntu 24.04 MATE LTS ("Noble Numbat") installation - in Launchpad, in the "subiquity" (Ubuntu installer) package section.

Here is the link to the Launchpad page with the current "subiquity" reported issues ("Bugs"), ordered by "Age" (most recent bugs appear first):

And here is the link to report a Bug for "subiquity":

I hope this helps at least somewhat. Please, keep us posted in this discussion topic :slight_smile:

It's much is looking like the storage controller on the motherboard is failing, so writing the system to disk is crashing. This is not a subiquity issue :confused:
