[Bug 1869814] [NEW] ubuntu-docs build failure - possible solution

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Gunnar Hjalmarsson (gunnarhj):

ubuntu-docs failed to build during the second Focal Fossa test rebuild:

https://launchpad.net/ubuntu/+archive/test-
rebuild-20200327-focal/+build/18982738

It was itstool which failed to generate the localized zh_CN pages. If
dropping zh_CN from ubuntu-help/Makefile.am, ubuntu-docs builds. But
excluding the Chinese pages is apparently not an acceptable solution.

The itstool package in focal {build-,}depends on python3. I built
itstool in a PPA with python2 instead, and in that PPA ubuntu-docs built
fine without modifications:

https://launchpad.net/~gunnarhj/+archive/ubuntu/ubuntu-docs/+packages

So the root cause seems to lie neither in ubuntu-docs nor itstool. I
would suspect that python3-libxml2 is buggy, but since itstool was built
against python2 in eoan, it's hard to tell if it's a regression.

Would building itstool against python2 be an acceptable workaround in
focal?
