According to Calamares' session.log of the failed installation it seems
that Calamares deactivates/closes the volume group just before trying to
mount it as the install target - which thus can't work. There is already
an upstream bug report about that behaviour that I'll link here
(currently closed, yet there is recent activity of people still
experiencing this kind of problem).

Title:
  Calamares fails to install on logical volume if no partition/LV is
  marked for being formatted

Bug description:
  SUMMARY

  On Kubuntu 24.04, Calamares fails to install if the following two
  conditions apply:

  * target / is on a Logical Volume (LVM)
  * no device is marked for being formatted

  STEPS TO REPRODUCE:
  1. Create a test VM set to UEFI mode (both Gnome Boxes and Virt Manager worked for me)
  2. Boot Kubuntu Noble daily image.

  #Preparing the disk
  3. sudo cfdisk /dev/vda
  4. Partition table: GPT
  5. New partition: 500M, Type: EFI System
  5. New partition: Rest of disk space, Type: Linux LVM
  6. Write partition table
  7. sudo mkfs.vfat -F 32 /dev/vda1 #format EFI partition
  8. sudo pvcreate /dev/vda2 #create physical volume
  9. sudo vgcreate kubuntu /dev/vda2 #create a volume group named 'kubuntu'
  10. sudo lvcreate -l 100%FREE -n kubuntutest kubuntu #create a logical volume named 'kubuntutest'
  11. sudo mkfs.ext4 /dev/kubuntu/kubuntutest #format the LV
  12. Reboot (might not be necessary).

  #Installation
  13. Start installer
  14. Select 'Manual Partitioning'
  15. Set /dev/vda1 as /boot/efi, keep data
  16. Set kubuntu/kubuntutest as /, keep data
  17. Start installation.

  OBSERVED RESULT
  After short time, Calamares fails with Error dialog:
  * "Extraction of cdrom/casper/filesystem.squashfs failed"
  * "rsync failed with error code 11"

  EXPECTED RESULT
  Installation process runs through successfully.

  ADDITIONAL INFORMATION
  If in step 15 "Formatting" is selected instead of keeping data (while all other steps aren't changed), the installation will be successful. If instead the root filesystem in step 16 is set to being formatted, installation will also work. So it seems this bug occurs only if there is no partition/LV being specified for formatting.
