[LVM issue] Installing Pop!Os 19.04 failed, could not install

[ValdikSS]

Distribution (run cat /etc/os-release):
Pop!_OS 19.04 generic ISO

Issue/Bug Description:
Pop!_OS 19.04 could not be installed in "clean install" mode if the HDD contains already installed Linux into LVM (Fedora 30 in my case).

Steps to reproduce (if you know):

1. Write Pop!_OS 19.04 ISO and boot it on the computer with existing Linux on LVM OS
2. Try to install Pop!_OS with full disk erasure

Expected behavior:
OS installs successfully

Actual behavior:
"Could not install"
"Installing Pop!_OS 19.04 failed"
partitioning error: vgchange failed with status: 5 (Input/output error (os error 5))

Other Notes:
Please see the attached log.

I had been trying several Linux distros, and found Pop!_OS to be the one that worked best for me right out of the box. But then it wouldn't install because a previously tested OS created LVMs.

The problem is, the installer uses part of the LVM toolset to try to remove the LVM volumes, but those tools are designed to fail out if the volumes aren't healthy--which is pretty much guaranteed to be the case when you're doing an erase-and-install.

I fought for several hours trying to get rid of those volumes, repartition the drive, and get Pop! to install. What finally solved it was to wait for more hours running dd to zero out my entire hard drive before running the Pop! installer again.

I think we need a tool that will quickly zap LVM off a hard drive when an erase-and-install is being performed.

Had the same issue,
what it work for me was erase the full disk with GParted and then do the install again.

Or if you want the terminal method take a look at the following guide: https://www.cyberciti.biz/faq/linux-remove-all-partitions-data-empty-disk/

Good Luck:)
