[Bug 1871689] Re: Installer hangs idle before populating root-fs with directories, "Saving installed packages..."

Reviewing the source it looks to be stalling in
partman/finish.d/apt_clone_save

I added 'set -x' to top of that file in the live system and captured the
following in its syslog. Looks like there's a failure to create the
root-fs directory structure and so there is no mountpoint for the /var/
file-system:

xubuntu at xubuntu:~$ ls -latr /tmp/tmp.GRbQsIC1FI/
total 20
drwx------  2 root root 16384 Apr  8 17:02 lost+found
drwxr-xr-x  3 root root  4096 Apr  8 17:02 .
drwxrwxrwt 20 root root   500 Apr  8 21:06 ..

** Description changed:

  Trying to install the Xubuntu 20200408 amd64 ISO from USB, Try (safe
  graphics mode) on Lenovo E495 (AMD Ryzen 7 mobile CPU) - not sure if the
  CPU might have something to do with this but probably not.
  
  Nothing obvious in the logs I've checked.
  
  Currently the system has been sitting idle for almost 2 hours with the
  ubiquity GUI showing "Saving installed packages...".
+ 
+ I'm doing a custom partitioning that I've done for years.
+ 
+ Before the installer is started I use gdisk to create the EFI-SP and 2
+ dm-crypt partitions for /boot/ and LVM respectively.
+ 
+ I use cryptsetup luksFormat --type=xxx ... on the partitions then open
+ them as LUKS_BOOT and LUKS_VG respectively.
+ 
+ I create the VG and several LVs for rootfs, var, home, usr_local.
+ 
+ I format each as ext4 with labels matching the LV name, and format
+ LUKS_BOOT as well.
+ 
+ I format the EFI-SP as vfat with FAT16.
+ 
+ In partman's "Something Else" I then select each LV and set its
+ mountpoint and do not choose to format it (again) since I wish to retain

  Installer hangs idle before populating root-fs with directories,
