Failed to load modules at startup: Could not find module by name 'off'

  • 772

I just upgraded from 15.04 to 15.10 and during the boot process I now get an error saying that some modules failed to load. So I ran systemctl status -l systemd-modules-load.service and I got this:

Oct 24 12:22:23 ubuntu systemd-modules-load[292]: Inserted module 'option'
Oct 24 12:22:23 ubuntu systemd-modules-load[292]: could not find module by name='off'

Oct 24 12:22:23 ubuntu systemd[1]: Failed to start Load Kernel Modules.
Oct 24 12:22:23 ubuntu systemd[1]: systemd-modules-load.service: Unit entered failed state.
Oct 24 12:22:23 ubuntu systemd[1]: systemd-modules-load.service: Failed with result 'exit-code'.

When I run cat /etc/modules I get

loop
lp
usbserial
option
nouveau
nouveau

I tried to comment out one of the nouveau modules but it didn't help.

I found a bug on Launchpad which gives a similar message but my problem doesn't seem to be caused by the rtc module (which is the culprit in the linked bug).

Anyone has an idea what I should try?

EDIT: added more info:

cat /lib/systemd/system/systemd-modules-load.service gives

[Unit]

cat /etc/modules-load.d/modules.conf gives the same output as cat /etc/modules/ listed above.

  1. Solved by commenting out (using the '#' character) both lines with nouveau in them in the /etc/modules file.

  2. Do the update then upgrade resolve my issue with fail load modules Even though I get

    Sub-process /usr/bin/dpkg returned an error code (1)" error [duplicate]

sudo apt-get update
sudo apt-get upgrade

    good luck

  3. Problem seems due to blacklisted nouveau and aliasing it to off in /etc/alternatives/x86_64-linux-gnu_nvidia_modconf after installing nvidia-304-updates in 16.04 amd64.

    The configuration inhibits the sequence to switch to nouveau driver by using:

    rmmod nvidia
modprobe nouveau

    Uncommenting the culprits enable to change the drivers of the nvidia graphic card without rebooting. The nouveau driver gets loaded properly then (but still no unity launcher or dash shown).

  4. To get a complete log from the service, you can also use

    journalctl -u systemd-modules-load.service

    So presumably you have something in /etc/modules (or possibly /etc/modules-load.d/) which refers to a nonexisting or broken module?

    Removing it from /etc/modules will solve your issue.

  5. I had to do this:

    sudo apt-get purge $(dpkg -l | grep nvidia | cut -f3 -d' ' | tr '\n' ' ')
