Comment 7 Alexander 2026-04-29 16:26:54 UTC
Due to this bug I am unable to install Fedora on my Acer laptop.

I used:
* "Fedora KDE Plasma Desktop 44" official release Live iso
* "Fedora Media Writer" USB creation tool

And there are steps to reproduce the bug using virtual machine (I used VirtualBox):

1. Attach "Fedora-KDE-Desktop-Live-44-1.7.x86_64.iso" to VM and boot
2. Create table/partitions using "KDE Partition Manager" or any other suitable tool:
   * Create GPT partition table on '/dev/sda' disk
   * fat32 - 512 MiB (for /boot/efi)
   * ext4 - 2 GiB (for /boot)
   * btrfs - all available space (for /)
   * apply all pending operations

   * I got partitions:
     * fat32 (/dev/sda1)
     * ext4 (/dev/sda2)
     * btrfs (/dev/sda3)

   * set 'boot' flag for fat32 (/dev/sda1) partition (via partition "Properties")
   * apply changes

3. Install system:
   * Launch desktop "Install to Hard Drive"
   * Language: "English (United States)" as default, press Next
   * Select "Mount point assignment", press Next
   * Select mount points:
     * "/" -> "btrfs.46" (got this btrfs name in VM) -> "Reformat" selected
     * "/boot/efi" -> "sda1" -> "Reformat" _NOT_ selected
     * "/boot" -> "sda2" -> "Reformat" selected
   * Press Next
   * Confirm "I understand that some existing data will be erased"
   * Click "Apply mount point assignment and install"

4. Wait and got 'anaconda' exception

Hello, all! 

Also I tested and encountered the same bug on the latest Fedora Desktop ISOs (v 1.7):
  * Workstation (Fedora-Workstation-Live-44-1.7.x86_64.iso)
  * KDE (Fedora-KDE-Desktop-Live-44-1.7.x86_64.iso)
  * xfce (Fedora-Xfce-Live-44-1.7.x86_64.iso)

Obviously, using the current anaconda version you can not install Fedora with a btrfs (default one) root partition and "Mount point assignments" installation type using Live ISO images.
