[Bug 946663] Re: Installer stuck at "Removing conflicting operating system files..."

[L. P. Luigi Espenlaub]

This problem continues amazingly in Lbuntu 16.10, 16.04.2 and Ubuntu 16.10
I say "amazingly" advisedly, as this bug has been around since at least Ubuntu 12.04 in 2012/04/11.
Consider renaming it Ubuntu based installers are cought in a loop at "Removing conflicting operating system files..."

The /home partition is the primary culprit, especially if doing an
install where you want to keep the data in it, mainly to save the time
needed for a restore, or possibly files missed in the backup.

The details pane only shows about six lines of messages at a time and I
was unable to copy and paste it to a file during the "Looping" install.
I have about 54 photographs of selected parts of the data scrolling
through the details pane. I can e-mail cropped copies or attempt to OCR
them and provide an rtf file if anyone is working on this.

There are two workarounds posted.

both referring to this "common bug"

by in the installer version of Gparted setting /home to "Do not use this
partition" My Lubuntu install finished

Title:
  Installer stuck at "Removing conflicting operating system files..."

Status in partman-target package in Ubuntu:
  Fix Released

Bug description:
  This is happening to me in both Ubuntu and Xubuntu 12.04 alpha install
  CDs.

  I have several partitions but I choose only two: one as the root (/)
  dir which I choose for formatting, and one as /home without
  formatting. Both are marked as ext4.

  The installer formats the root partition and then it says "Removing
  conflicting  operating system files..." and it never leaves that
  state.

  Before running the installer, I install the "Broadcom STA wireless"
  drivers and enable my wifi connection.
