Hi,

Sharlatan Hellseher <sharlatanus <at> gmail.com> skribis:

> * gnu/packages/astronomy.scm (alfa): New variable.

I passed it through ‘guix style’ and changed the license to ‘gpl3’
because source headers specify “v3”, without the “or any later version”
wording.

According to <https://qa.guix.gnu.org/issue/59323> it’s failing on
aarch64-linux and succeeds everywhere else; could you investigate why as
the next step and report it upstream?

Applied, thanks!

Ludo’.
