It will build stuff if it can't find a substitute (not an error). '--fallback' is only required when substitution fails (an error). That particular test failure was a bug in GnuPG's test suite that we worked around: http://git.savannah.gnu.org/cgit/guix.git/commit/?id=d404a6f9711c8dcc1cc6cf55d8c07901aa450192 Code with an expiration date is very annoying! It sounds like you will need to use `guix pull`. What do others think? Should we mention `guix pull` in the installation documentation? I'm skeptical for reasons described upthread. I think the real bug is that the installation image becomes brittle as time passes (so I changed the subject of my reply). Does anyone have ideas to mitigate this? Can we tweak the mirrors? Will this become less pressing when we have more storage space and can store substitutes for a longer period?
