Guix,

Two simultaneous =E2=80=98guix weather=E2=80=99s on the same machine will s=
tep on=20
each others' toes and die.

They were running in two separate repositories, both vanilla=20
sv:guix, one at v0.15.0, the other on master (7a7c91a).

Both aborted like this:

=CE=BB ./pre-inst-env guix weather=20
--substitute-urls=3Dhttps://munich.tobias.gr
  computing 7,850 package derivations for x86_64-linux...
  looking for 8,167 store items on https://munich.tobias.gr...
  updating substitutes from 'https://munich.tobias.gr'...=20
  19.7%[my \n]
  guix weather: error: rename-file: No such file or directory

The second one displayed a different percentage and package count=20
but was otherwise identical.

Kind regards,

T G-R
