Source: astropy Version: 3.2.1-1 Severity: serious Justification: autopkgtest regressions block migration Affects: sunpy/0.9.6-2 User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu eoan autopkgtest
Hi Ole,
The sunpy autopkgtests fail with new astropy 3.2.1-1, and considering the
failing autopkgtest is one specifically intended to test an error-prone
astropy transformation (according to the comments), this looks to me like it
may be a genuine regression in astropy that's caught by sunpy:

Opening a bug so that this is documented in the BTS (and so it can be
reassigned if I'm wrong about which package is to blame).
