[Bug 1736309] Re: installer failed missing dpkg_1.19.0.4ubuntu1_amd64.deb

[Jb]

Update #2 for 2017-December 05 isos:
Lubuntu Alternate 64 = fail
Lubuntu Desktop = works
Ubuntu Server = fails

Install breaks due to chroot failing.  
Chroot fails because /target/lib64/ld-linux-x86-64.so.2 is not installed on target drive.

Not sure why that file is not copied over.

Lubuntu Alternate failing line:
chroot /target dpkg-deb -f /var/cache/apt/archives/dpkg_1.19.0.4ubuntu1_amd64.deb Version

The chroot error is "no such file or directory", but this is really
because of missing /target/lib64/ld-linux-x86-64.so.2

Ubuntu server install halts at:
chroot: can't execute 'dpkg-divert': No such file or directory

If I open another terminal with f2:
cp /lib64/ld-linux-x86-64.so.2 /target/lib64

Then I can manually run the "chroot /target dpkg-deb -f
/var/cache/apt/archives/dpkg_1.19.0.4ubuntu1_amd64.deb Version" on
Lubuntu alternate without the "No such file or directory" error.

not sure how to debug further.

  Failure with daily:
  Lubuntu Daily Alternate 2017 December 04
  SHA256 hash of file .\lubuntu-18.04-alternate-amd64.iso:
  bd8777489df3159c356879752bbc47e1805e4740d291fe4be6413afba10a6496

  Installer fails with:
  Warning: Failure trying to run: chroot /target dpkg-deb -f /var/cache/apt/archives/dpkg_1.19.0.4ubuntu1_amd64.deb

  I switched to another virtual console with F2 and looked under
  /target/var/cache/apt and there's no such deb file.

  I don't know when this stopped working, but I know the daily on 2017
  November 11th worked fine.
