Unable to upgrade guix

Guix

When I try to upgrade guix I recieve this error:

$ guix upgrade

...

P.S. is there a reason why upgrades and pulls take such a long time compared to other Linux repositories?

Normally, I do

guix pull && guix package -u

For upgrade, I do reconfiguration.

Looks like there’s a –do-not-upgrade option.

$ guix upgrade --do-not-upgrade='icedove|ungoogled-chromium'

How is it possible to fail to build a source package from guix channel? I thought every package from guix channel is supposed to be built successfully everywhere.
