I ran “guix locate” on the HPC cluster where we generally don’t ever run
“guix gc”.  Here’s what I got:

--8<---------------cut here---------------start------------->8---
$ time guix locate ls
guix locate: indexing files from /gnu/store...
guix locate: traversing local profile manifests...
guix locate: error: unsupported manifest format

real	2m24.029s
user	3m11.519s
sys	0m5.617s
--8<---------------cut here---------------end--------------->8---

It would be good if it printed the location of the problematic manifest
and ignored it.

Oooh no…

Yes.

However, how can it happen?  ‘guix locate’ knows all the manifest format
version, so maybe it mistook a file for a manifest when in fact it’s
something else?

Could you ‘strace -o /tmp/log.strace guix locate ls’ to get the name of
the offending file for now?

Thanks for reporting it!

The last manifest it reads is
/gnu/var/guix/profiles/per-user/wneuber/guix-profile-1-link/manifest
with the following contents

--8<---------------cut here---------------start------------->8---
(manifest
  (version 1)
  (packages
    (("gcc"
      "4.9.2"
      "out"
      "/gnu/store/ym7sybrdifnm3g0rafhclv891niaczcv-gcc-4.9.2"
      ()))))
--8<---------------cut here---------------end--------------->8---

Woow, this profile predates May 2015 and commit
dedb17ad010ee9ef67f3f4f3997dd17f226c8090.  And indeed, it’s no longer
recognized since e7e04396c0e91569bf493e1352d6539babc15327 (July 2022).

I’ll work on a fix…

Thank you!  I confirm that it is now successfully indexing all packages
on the cluster.
