Hello everyone I recently ran into this issue and couldn't figure out the solution. The error: [FAILED] Failed to load Kernel modules on a Raspi 3 b+ , running the latest Ubuntu during bootup. Once you're to the desktop, terminal :
There should be a few .conf files in there, for me the issue was in the "cups-filter.conf" which some others you might see are "modules.conf" "raspi.conf" There were 3 printer drivers that were causing issues, so I just commented them out, one was llp, parport_pc, and something else. Once I rebooted I no longer receive the [FAILED] error. Hope this helps!
