Lintian failure on Debian 10

[pugnascotia]

We added Debian 10 to the packaging tests for #44657. Now those tests are failing, as below.

We are getting all kinds of nasty errors and warning related to issues setting the default locale on Debian 10. I think I've tracked down the problem. I've opened https://github.com/elastic/infra/issues/15670 to have this addressed.

I don't think the locale errors are causing this.
I'm getting this with locales-all installed.

I think the root cause is

Usage: Lintian::files::empty_package::_set_is_dummy(self, newvalue) at /usr/share/lintian/checks/files/empty-package.pm line 44.

which is indicative of a a bug in lintian.

Also of note:

jenkins@alpar-ci-debian-10-1029-0746:~/elasticsearch$ lintian --version
Lintian v2.30.0

According to https://packages.debian.org/search?keywords=lintian that's the version in testing, debian 10 should have 2.15.0

Running sudo apt-get install lintian=2.15.0 to get the correct version works.

We have a miss configured source

jenkins@alpar-ci-debian-10-1029-0746:~/elasticsearch$ cat /etc/apt/sources.list.d/deb_debian_org_debian.list 
deb http://deb.debian.org/debian unstable main
jenkins@alpar-ci-debian-10-1029-0746:~/elasticsearch$ apt-cache showpkg lintian
Package: lintian
Versions: 
2.30.0 (/var/lib/apt/lists/deb.debian.org_debian_dists_unstable_main_binary-amd64_Packages)

[alpar-t]

The workaround was merged to stop the CI failures, will keep the issue open to track removing it once the image is fixed.

Different Lintian versions check different things, that's why this was particular to Debian 10.
