Merge sagemath 8.1-2 (universe) from Debian unstable (main)

[Amr Ibrahim]

Please merge sagemath 8.1-2 (universe) from Debian unstable (main)

I can't work on this merge myself. I'm filing this for reference.

Explanation of the Ubuntu delta:
  * Add u1-more-sphinx-1.5-fixes.patch to fix build with Sphinx 1.5.
  * Drop unneeded debian/rules changes from the last uploads.
  * Merge from Debian unstable. Remaining changes:
    - Match lcalc versioning to the latest ubuntu one. (Can be
      dropped in next sync of lcalc)

Changelog entries since current bionic version 8.0-10ubuntu1:

sagemath (8.1-2) unstable; urgency=medium

  * Upload to unstable.

Already sync'd, but FTBFS.

Nothing to sponsor here, unsubscribing ubuntu-sponsors.

[Gianfranco Costamagna (costamagnagianfranco)]

It is now syncable, but still FTBFS.
I don't see the need of a merge, unless you want to provide a patch
(it is currently broken in Debian too BTW)
