Bug Description

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 the labels.

I get passed the User Info questions then it idles whilst showing "Saving installed packages...".

The root file-system directory structure hasn't been created:

root@xubuntu:~# mount | grep rootfs
/dev/mapper/ELLOE00-rootfs on /tmp/tmp.woX6753mbL type ext4 (rw,relatime)

root@xubuntu:~# find /tmp/tmp.woX6753mbL/
/tmp/tmp.woX6753mbL/
/tmp/tmp.woX6753mbL/lost+found

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@xubuntu:~$ ls -latr /tmp/tmp.GRbQsIC1FI/

Solution:

Create all the mountpoints in the root-fs when doing a manual install.

e.g:

sudo mkdir -p /target/{proc,sys,dev/pts,var,home,boot,usr/local}
