I’m not sure but it may have been caused by a hung “guix publish”
process.  This could have given you bad substitutes, which have been
added to your cache at “/var/guix/substitute/cache/”

Others have reported it but I couldn’t reproduce it on my main machine.
This makes me think that it may have been a temporary issue with effects
on the local cache.

You may need to delete your substitute cache under
“/var/guix/substitute/cache/”.  jsierles on IRC reported that this fixed
their issue.

Could you please try that and report back?
