Failed to start Load Kernel Modules after upgrading to Ubuntu 18.04

Question

After I upgrade Kubuntu from 17.10 to 18.04, and restarted it, all I'm seeing is my mouse cursor, which responds to my movements, and that's pretty much it. I tried to see if I can start up sddm, but that failed.

After running journalctl -xe, this is the entry when it tried to start up systemd-modules-load.service:

systemd-modules-load[1858]: Failed to find module 'ashmem_linux'
systemd-modules-load[1858]: Failed to find module 'binder_linux'
systemd[1]: systemd-modules-load.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: systemd-modules-load.service: Failed with result 'exit-code'
systemd[1]: Failed to start Load Kernel Modules

I also checked /etc/modules, but they're empty.

I tried disabling Secure Boot from Lenovo's BIOS, but it won't let me (the option is disabled).

I tried running sudo dpkg --configure -a, but that didn't work, and neither did sudo apt install -f.

The solution I tried: https://askubuntu.com/a/779574/558318

I tried mokutil --disable-validation, but that didn't work at all, either.

dmesg | grep -i failed returns this:

This original problem got solved by purging anbox, but it seems that that wasn't the problem at all. See here

Solution

Open a terminal Ctrl+Alt+T and run:

sudo apt-get purge anbox-*

Are you able to get to the GRUB menu, or the login screen? If you're able to get to the login screen, click on your username, then the gear icon, and tell me which environment is selected.

I'm only able to get to the GRUB menu. The only thing I'm seeing on my login is my mouse cursor on a black screen. @heynnema

Are you able to get into Recovery Mode from the GRUB menu?

[YamiYukiSenpai]

yup. However, I can't connect to my network unless I use a wired connection

[YamiYukiSenpai]

that solved the Load Kernel Modules problem, but that wasn't the problem after all :-(

Agreed. Having the same issue. I have to login manually and initiate startx to execute X server
