@pllim, I think I saw a note about this go by in the astropy-dev mailing list. Is it straightforward to fix? Can we make astropy-asdf an optional package?

[pllim]

It's a known upstream issue. A fix will go in tomorrow in astropy one way or another. Thanks for your patience!

• astropy/astropy#12929
• astropy/astropy#12930

[pllim]

Should be fixed in astropy dev now. There is no action required here. Next run should pass.
