"error: make-custom-binary-output-port: unbound variable" after guix home reconfigure

Hello everyone!

I have somehow managed to get my Guix install into an erroneous state.

After running a "guix home reconfigure" I now get this error backtraces error everytime I try to to anything with guix except "guix --help". Which also means I can't do a roll-back (or at least I have not managed to do it).

I'm running Guix on a foreign distro (Debian container on a Chromebook).

dev@penguin:~ $ guix pull

This is the third time I have managed to get into this state.

The first time I had to uninstall and re-install Guix completely, which fixed it. The second time I had Guix installed in to "~/guix-profile/bin" and could use that to roll-back my home environment.

But this time I don't have that. So I would appreciate any guidance on how to diagnose this and if there are way to get my out of this state without having to uninstall and re-install Guix.

I now managed to get the same state on my GuixSD machine.

I can do a "sudo guix system reconfigure" but I can't handle my users guix command.

Are re-installation the only option?

Hello Kristofer. Even though I do not understand at all how to get into

such a state, it appears using an older guix has helped you before, so

you could try running

/var/guix/profiles/per-user/dev/current-guix-<SOME-NUMBER>-link/bin/guix

instead of guix.

Hi Florian

Thanks for the response.

With your help I managed to fix my GuixSD install at least.

I couldn't use the "/var/guix/profiles/per-user/dev/current-guix-<SOME-NUMBER>-link/bin/guix" they gave me the same error. But I noticed that there where older Guix Home configuration laying around there and after activating one of those I could roll-back.

I think the issue was that I had added "guile-next" to my Guix Home config.
