zmaint No, I don't ever make it to a desktop environment. I boot the live CD, get an option "Install Solus", which then gives the nouveau error and freezes. However, from the nouveau error I can use Ctrl-Alt-F2 to access a CLI, which I could use to update, except that the partition with the live CD on it is too small for the update (And I don't know how to successfully expand the partition). So my thought was, if there was a CLI based installer (Debian has this I think?), I could install to a larger disk, then be able to run the update.
Basically, I have access to no DE, only a CLI, and less than 1 GB free space for updates.
