- Asus Zenbook 14 UX433FN (NVMe PCIe SSD)
- Ubuntu 18.10 and Windows 10 dual boot, Windows 10 working fine.
Today my Ubuntu 18.10 suddenly gave me a "purple screen of death" after I closed my laptop lid (ie. it couldn't wake up from suspend).
After which, I forced shutdown and tried to reboot (both normally and with recovery mode), and both times it got stuck at
Loading initial ramdisk...
After this I successfully reinstalled Ubuntu 18.10 using CD. TWICE.
Each time, after successfully installing graphics drivers and everything, Ubuntu automatically prompts me to do security updates etc. Before installing updates, I can use and boot into Ubuntu normally.
BUT after installing these updates successfully, and rebooting, I get stuck at
Loading initial ramdisk... again.
After my third re-installation, I decided to do
sudo apt upgrade from command line directly instead of the GUI as I did previously.
I got the same error again!
This hints at the possibility of a bug or broken package in the apt repository. As this is a fresh Ubuntu 18.10 install, this is extremely puzzling.
- Use LiveCD as per https://help.ubuntu.com/community/LiveCdRecovery#Update_Failure.
- Update kernels before installing.
Why is this so? Is there a bug in the update repositories somewhere?
I can use Ubuntu without updating of course, but this leaves my computer vulnerable to security issues. In the long-run, being afraid of updating the computer lest I get this same error is quite stupid.
A bug report has been filed. Apparently I'm not the only one affected.
acpi_osi=off might work.
Apparently, this might be due to a known bug in Asus.
