dpkg: error: --compare-versions takes three arguments: <version> <relation> <version>

[Heinrich Schuchardt]

I used autopkgtest 5.34ubuntu2 on Oracular

   sh -x /usr/bin/autopkgtest-build-lxd ubuntu-daily:noble/amd64

It fails with

+ REUSE=
+ [ lxc = incus ]
+ lxc version
+ sed -ne s/Client version: // p
+ dpkg --compare-versions 5.21.1 LTS ge 5.14
dpkg: error: --compare-versions takes three arguments: <version> <relation> <version>

We need to remove the LTS postfix.

In salsa.debian.org the problem is already fixed:

tools/autopkgtest-build-lxd:256:
if [ "$COMMAND" = incus ] || dpkg --compare-versions "$(lxc version | awk '/Client version:/{print$3}')" ge 5.14; then
