Comment (by ShadSterling):

 without `-v -d` the output ends with
 {{{
 ===>  Computing dependency order
       [                                        ]  82.6 %Warning: All

 Error: process_cmd failed: can't read "variants": no such variable
 }}}

 Before #70869 was fixed there were lots of errors, none of which brought
 the whole thing to a halt without any attempts to install anything or any
 further output.
 (I don't expect that fix was related, it's just what prompted the retry)

 Now it never tries to install anything, it ends there, leaving everything
 deactivated, which leaves my system nearly unusable.

 Is that really the intended behavior?
