Linux Kernel Rollback Instructions
Raw
kernel_rollback.md

Some users are reporting Kernel Panics (Purple Screen) after upgrading to the kernel 7.0.0-28 generic.

To solve this, you need to roll back to an older kernel version. This is accomplished following those steps:

  1. Reboot the computer. The GRUB menu should open after the failed boot
  2. Select advanced options
  3. Select a kernel other than the affected one and press ENTER

The system should boot as normal.

Once you gain access, remove the affected kernel as following:

  1. Open the Update manager
  2. Click in Show > Linux Kernels
  3. Click in Continue
  4. Click in Remove Kernels
  5. Select the Kernel version with problem (7.0.0-28 in this case) and click in Apply.
  6. After it finish, reboot your computer.
  7. If prompted again, DON'T update the kernel to the version with problem, wait when there is a even newer version that probably will bring fixes to this issue.
