I ran:

--8<---------------cut here---------------start------------->8---
guix pull --substitute-urls=https://ci.guix.gnu.org
--8<---------------cut here---------------end--------------->8---

and moreover...

... with

--8<---------------cut here---------------start------------->8---
guix pull --fallback
--8<---------------cut here---------------end--------------->8---

I still get the same error.

The only solution I've come up with looks like:

--8<---------------cut here---------------start------------->8---
#!/bin/bash

for (( ; ; ))
do
    echo "Press CTRL+C to stop..."
    guix pull 2>&1 | tee /tmp/log.txt
    $(grep failed /tmp/log.txt | cut -d' ' -f3) && \
        if [ 1 ]
        then
	    break
        fi
    echo "Building:"
    echo $(grep failed /tmp/log.txt | cut -d' ' -f3)
    sleep 1
    guix build $(grep failed /tmp/log.txt | cut -d' ' -f3)
done
--8<---------------cut here---------------end--------------->8---

where I basically I keep manually rebuilding the
failed drv again and again subsequently until the
operation finishes. I get the same error during
"upgrades"  and also when installing a package :(
