Aloha Guix,

A number of errors have appeared on my system. Notably I have the following
issue with "sudo guix system reconfigure $CONFIG_FILE":
"guix system: error: error parsing derivation
`/gnu/store/8jqz1m1src0h4md70q09rlxppdy6d1jx-activate-service.scm.drv':
expected string `Derive(['"

I believe this is due to key files on my system (e.g.
"/gnu/store/...-activate.scm.drv" and
"/gnu/store/...-activate-service.scm.drv") have become both empty and live
on my system.

Here is the result of trying to repair using "guix gc"
"zjabbar <at> tao ~$ sudo guix gc --verify=contents,repair

It looks like a lot of files have the same hash and are empty. Is the only
way to fix this to reinstall Guix? Is it known why this could happen in the
first place?

I guess a power outage or the like.  Currently the guix daemon never
calls 'sync' or the like (except possibly for the SQlite db), though
maybe it should (at cost of some performance).

That's a way to do it, but there are less heavy-handed ways.  E.g.,
maybe "guix gc --verify=repair" could be extended to delete objects
that are broken (wrong hash) and aren't referenced? (long-term)

For the short term, maybe do "guix gc", possibly some of the broken
files are unused.

Greetings,
Maxime.

Nice, closing.

FWIW, you can close reports yourself by sending to
NNNNN-done <at> debbugs.gnu.org instead of NNNNN <at> debbugs.gnu.org.

Aloha Maxime Devos,

Your suggestion worked! I did the following but I'm not sure how much was
actually needed:

1. Use guix pull and guix system to switch to an older generation (I did
like -100)
2. Use guix gc
3. Run guix system again which remakes the files (like activate.scm as per
title)

This time guix system actually runs to completion. Mahalo nui iā ʻoe!
