[Bug 1698980] Re: Can't install on trusty arm64 chroot

[Dimitri John Ledkov]

To install crossbuild-eseential-$foo, one needs to:
1) enable $foo in dpkg
2) add apt sources for $foo arch
3) apt update.

The three apt lines look good.
Was arm64 added in dpkg? E.g. $ sudo dpkg --add-architecture arm64 ?

Note, I'm on xenial, and I can't remember if foreign architecture
handling in dpkg was done differently check your manpage.

Also why use trusty instead of xenial?
