Bug#916586: sagemath: depends on specific libsingular4 which is no longer being built in unstable

[Julian Gilbey]

Package: sagemath
Version: 8.4-2
Severity: serious

Hello,

I don't know whether this is an easy issue to fix or not (I hope it's
easy).  sagemath currently depends on a very specific version of
libsingular4, but the singular now in unstable only builds
libsingular4m1; as far as I can tell, no source package in unstable
now builds libsingular4.

So sagemath will need to be updated to link to libsingular4m1, if that
is possible.

Thanks for all your work on this package!

Best wishes,

   Julian
