Problem between asdf and sunpy
On my system, trying to save an astropy table to asdf raises this :
DistributionNotFound: The 'parfive[ftp]>=1.1.0' distribution was not found and
is required by the application
This happens when asdf parses the asdf_extensions entry points and try to
execute them. This can be manually done with:
for ep in iter_entry_points(group="asdf_extensions"):
ext = ep.load()
Installing python3-parfive does not solve the problem because the package does
not contain the ftp module and the error becomes:
UnknownExtra: parfive 1.1.1 has no such extra feature 'ftp'
Do you think I should report the bug against asdf or sunpy?
