lsb_release fails in classic (arm64)

[Michi Henning]

I'm getting this when running lsb_release with classic on a Dragonboard:

$ lsb_release -a
Traceback (most recent call last):
  File "/usr/bin/lsb_release", line 95, in <module>
    main()
  File "/usr/bin/lsb_release", line 59, in main
    distinfo = lsb_release.get_distro_information()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 383, in get_distro_information
    distinfo = guess_debian_release()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 281, in guess_debian_release
    get_distro_info(distinfo['ID'])
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 41, in get_distro_info
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 41, in <lambda>
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))

I see this even without classic. Curiously my traceback is different:

zyga@dragon-1:~$ lsb_release
Traceback (most recent call last):
  File "/usr/bin/lsb_release", line 95, in <module>
    main()

    distinfo = guess_debian_release()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 281, in guess_debian_release

lsb_release is not supposed to be working in core (it should not even be shipped, but there is an issue with a dependency from cloud-init) ...

that said, it should work in the classic dimension if it is installed there though.

potentially a duplicate of Bug #1650207 (for which a fix was just uploaded for the edge channel)

I think this bug is not related to Bug #1650207, but same as bug #1662357.
