[Debian-science-sagemath] Next sagemath 8.4 upload (matplotlib 3.0.2 now in unstable)

[Tobias Hansen]

Hi,

since gap in unstable has the patches required by sagemath since yesterday, I was working on the next sagemath upload. After updating the gap-4.10 patch (in dd756fc1) I got some errors that should be fixed by installing additional gap packages. The change in the patch reflects that now more gap packages should be installed, as discussed in https://trac.sagemath.org/ticket/22626. We could also go back to the older version of the patch, which just had this one error in the indep doctests (where we don't allow errors) to be dealt with:

sage -t --long --warn-long 70.2 src/doc/en/constructions/groups.rst
**********************************************************************
File "src/doc/en/constructions/groups.rst", line 187, in doc.en.constructions.groups
Failed example:
    print(gap.eval("normal := NormalSubgroups( G );"))
Expected:
    [ Sym( [ 1 .. 4 ] ), Alt( [ 1 .. 4 ] ), Group([ (1,4)(2,3), (1,3)(2,4) ]),
      Group(()) ]
Got:
    [ Sym( [ 1 .. 4 ] ), Alt( [ 1 .. 4 ] ), Group([ (1,4)(2,3), (1,2)(3,4) ]), 
      Group(()) ]

Today I found that there's yet another problem now: matplotlib 3.0.2 was uploaded to unstable today, leading to many errors of this kind during the docbuild:

If someone else could help looking at this it would be appreciated, since I don't have much time these days.

Best,
Tobias
