That's what I meant to tell you in my first reply, sorry if it was
unclear. I think changing the dependency to
"lxc-templates | lxc ( << 1:3 )" is what you want here.
See deb-version(7) for how dpkg (and apt) compares versions.
Cheers,
Sven

I am maintaining a set of meta packages, referencing the packages
to install on my hosts. To avoid having separate meta packages for
each new Debian version I have to use conditional dependencies, like
Package: sample-setup
Architecture: all
Depends: ${misc:Depends}
, sample-setup-chroot
:
, nvme-cli | base-files ( << 9 )
:
Meaning nvme-cli has to be installed for Debian 9 or newer.
This package
Package: sample-lxc
Architecture: all
Depends: ${misc:Depends}
, cgmanager | systemd
, debootstrap
, lxc
, lxc-templates | lxc ( << 3 )
:
did not work as expected (IMHO), apparently because (1:2 << 3) = false.

Hello, perhaps options described here could help you: https://www.debian.org/doc/manuals/aptitude/ch02s05s05.en.html

You don't, at least as long as there is only an lxc package _with_ the epoch available, like the one you have currently installed. I am not sure I understand what you actually want to do, though.

Note the epoch. $ dpkg --compare-versions 1:2.0.11-1~xgo90+1 lt 3 || echo 'Got it!' Got it! Maintaining the sample-lxc package I have no influence upon other packages introducing new epoch numbers. Upstream moved the templates into a separate github repository for lxc version 3, so its unreasonable to consider Debian's epoch number for package dependencies in this case. How can I express this dependency upon lxc's upstream version number in my control file, ignoring the epoch number? This is just out of interest. The workaround for my package is obvious.

I am surprised to read that, considering that your installed lxc version
does not actually fulfill the dependency. Note the epoch.
$ dpkg --compare-versions 1:2.0.11-1~xgo90+1 lt 3 || echo 'Got it!'
Got it!
