debootstrap --variant=fakechroot --arch=i386 impossible on amd64

[Ken Sharp]

It is simply impossible to create an i386 chroot using fakechroot on a Trusty amd64 installation. This variant has been broken for a billion reasons since I started using Ubuntu.

$ fakeroot fakechroot debootstrap --arch=i386 --variant=fakechroot trusty ~/chroot-trusty-i386 http://localhost:3142/gb.archive.ubuntu.com/ubuntu/

And again...

fakechroot: preload library not found, aborting.

I give up at this point.

Status changed to 'Confirmed' because the bug affects multiple users.

Two years. Nobody cares.

Still doesn't work.

[Ken Sharp (kennybobs)]

Fixing /bin/fakeroot fixes this issue. Needs fixing upstream. Will update.

[Ken Sharp (kennybobs)]

Waiting to upload the fix for fakeroot, but working around that...

I needed a bunch of new dependencies.

$ sudo apt install libattr1:i386 libacl1:i386 libaudit1:i386 libdebconfclient0:i386 libsemanage2:i386 libxml2:i386 libcap2:i386 libicu70:i386 libpam0g:i386

Then I had to work around Bug #1430891.

$ fakeroot fakechroot debootstrap --variant=fakechroot --arch=i386 --exclude=systemd-timesyncd jammy jammy-fakechroot

Where I hit:

dpkg: dependency problems prevent configuration of console-setup-linux:
 console-setup-linux depends on kbd (>= 0.99-12) | console-tools (>= 1:0.2.3-16); however:
  Package kbd is not installed.
  Package console-tools is not installed.

console-tools does not exist, and kbd is not built for i386: Bug #2052399
